Fixes error: no matching constructor for initialization of
'std::pair<std::__cxx11::basic_string<char>, std::__cxx11::basic_string<char> >'
with older toolchain (clang/libcxx) on Ubuntu 16.04. The issue is the
StringRef-to-std::string conversion.
This applies the same fix that D84748 did for macro definitions.
Appropriate include path is now automatically set for all libraries
which link against gtest targets, which avoids the need to set
include_directories in various parts of the project.

Breakpad creates minidump files that can a module loaded multiple times. We found that when a process mmap's the object file for a library, this can confuse breakpad into creating multiple modules in the module list. This patch fixes the GetFilteredModules() to check the linux maps for permissions and use the one that has execute permissions. Typically when people mmap a file into memory they don't map it as executable. This helps people to correctly load minidump files for post mortem analysis.

Since a842950b62 this test started using
the reproducer subsystem but we never initialized it in the test. The
Subsystem takes an argument, so we can't use the usual SubsystemRAII at the
moment to do this for us.
This just adds the initialize/terminate calls to get the test passing again.
Extract all the provider related logic from Reproducer.h and move it
into its own header ReproducerProvider.h. These classes are seeing most
of the development these days and this reorganization reduces
incremental compilation from ~520 to ~110 files when making changes to
the new header.
This patch adds support for emitting multiple abbrev tables. Currently,
compilation units will always reference the first abbrev table.

Similarly to D85836, collapse all Scalar float types to a single enum
value, and use APFloat semantics to differentiate between. This
simplifies the code, and opens to door to supporting other floating

The class contains an enum listing all host integer types as well as
some non-host types. This setup is a remnant of a time when this class
was actually implemented in terms of host integer types. Now that we are
using llvm::APInt, they are mostly useless and mean that each function
needs to enumerate all of these cases even though it treats most of them
identically.
I only leave e_sint and e_uint to denote the integer signedness, but I
want to remove that in a follow-up as well.
Removing these cases simplifies most of these functions, with the only
exception being PromoteToMaxType, which can no longer rely on a simple
enum comparison to determine what needs to be promoted.
This also makes the class ready to work with arbitrary integer sizes, so
it does not need to be modified when someone needs to add a larger
integer size.

These definitions are needed by any file which uses gtest. Previously we
were adding them in the add_unittest function, but over time we've
accumulated libraries (which don't go through add_unittest) building on
gtest and this has resulted in proliferation of the definitions.
Making this a part of the library interface enables them to be managed
centrally. This follows a patch for -Wno-suggest-override (D84554) which
took a similar approach.

Summary:
Initially, Apple simulator binarie triples didn't use a `-simulator`
environment and were just differentiated based on the architecture.
For example, `x86_64-apple-ios` would obviously be a simualtor as iOS
doesn't run on x86_64. With Catalyst, we made the disctinction
explicit and today, all simulator triples (even the legacy ones) are
constructed with an environment. This is especially important on Apple
Silicon were the architecture is not different from the one of the
simulated device.
This change makes the simulator part of the environment always part of
the criteria to detect whether 2 `ArchSpec`s are equal or compatible.

Summary:
This commit is somewhat NFC-ish today as the environment of triples
is not considered when comparing s if one of them is
not set (I plan to change that).
We have made simulator triples unambiguous these days, but the
simulator platforms still advertise triples without the
environment. This wasn't an issue when the sims ran only on
a very different architecure than the real device, but this
has changed with Apple Silicon.
This patch simplifies the way GetSupportedArchitectureAtIndex
is implemented for the sim platforms and adds the environment.
It also trivially adds support for Apple Silicon to those
platforms.

The function didn't combine a large entry which overlapped several other
entries, if those other entries were not overlapping among each other.
E.g., (0,20),(5,6),(10,11) produced (0,20),(10,11)
Now it just produced (0,20).
This was originally reverted because the m_valid member in TypeMatcher was
unused in builds with disabled asserts. Now the member is gone and the default
constructor is deleted (thanks Eric for the idea!).
Summary:
FormattersContainer stores LLDB's formatters. It's implemented as a templated
map-like data structures that supports any kind of value type and only allows
ConstString and RegularExpression as the key types. The keys are used for
matching type names (e.g., the ConstString key `std::vector` matches the type
with the same name while RegularExpression keys match any type where the
RegularExpression instance matches).
The fact that a single FormattersContainer can only match either by string
comparison or regex matching (depending on the KeyType) causes us to always have
two FormatterContainer instances in all the formatting code. This also leads to
us having every type name matching logic in LLDB twice. For example,
TypeCategory has to implement every method twice (one string matching one, one
regex matching one).
This patch changes FormattersContainer to instead have a single `TypeMatcher`
key that wraps the logic for string-based and regex-based type matching and is
now the only possible KeyType for the FormattersContainer. This means that a
single FormattersContainer can now match types with both regex and string
comparison.
To summarize the changes in this patch:
* Remove all the `*_Impl` methods from `FormattersContainer`
* Instead call the FormatMap functions from `FormattersContainer` with a
`TypeMatcher` type that does the respective matching.
* Replace `ConstString` with `TypeMatcher` in the few places that directly
interact with `FormattersContainer`.
I'm working on some follow up patches that I split up because they deserve their
own review:
* Unify FormatMap and FormattersContainer (they are nearly identical now).
* Delete the duplicated half of all the type matching code that can now use one
interface.
* Propagate TypeMatcher through all the formatter code interfaces instead of
always offering two functions for everything.
There is one ugly design part that I couldn't get rid of yet and that is that we
have to support getting back the string used to construct a `TypeMatcher` later
on. The reason for this is that LLDB only supports referencing existing type
matchers by just typing their respective input string again (without even
supplying if it's a regex or not).

add_compile_options is more sensitive to its location in the file than add_definitions--it only takes effect for sources that are added after it. This updated patch ensures that the add_compile_options is done before adding any source files that depend on it.
Using add_definitions caused the flag to be passed to rc.exe on Windows and thus broke Windows builds.
After lots of follow-up fixes, there are still problems, such as

This patch adds Clang's new (and GCC's old) -Wsuggest-override to the warning flags for the LLVM build. The warning is a stronger form of -Winconsistent-missing-override which warns _everywhere_ that override is missing, not just in places where it's inconsistent within a class.
Some directories in the monorepo need the warning disabled for compatibility's, or sanity's, sake; in particular, libcxx/libcxxabi, and any code implementing or interoperating with googletest, googlemock, or google benchmark (which do not themselves use override). This patch adds -Wno-suggest-override to the relevant CMakeLists.txt's to accomplish this.

Summary:
Currently the frame recognizers are stored in a global list (the list in the
StackFrameRecognizersManagerImpl singleton to be precise). All commands and
plugins that modify the list are just modifying that global list of recognizers
which is shared by all Target and Debugger instances.
This is clearly against the idea of LLDB being usable as a library and it also
leads to some very obscure errors as now multiple tests are sharing the used
frame recognizers. For example D83400 is currently failing as it reorders some
test_ functions which permanently changes the frame recognizers of all
debuggers/targets. As all frame recognizers are also initialized in a 'once'
guard, it's also impossible to every restore back the original frame recognizers
once they are deleted in a process.
This patch just moves the frame recognizers into the current target. This seems
the way everyone assumes the system works as for example the assert frame
recognizers is using the current target to find the function/so-name to look for
(which only works if the recognizers are stored in the target).

Summary:
On macOS 11, the libraries that have been integrated in the system
shared cache are not present on the filesystem anymore. LLDB was
using those files to get access to the symbols of those libraries.
LLDB can get the images from the target process memory though.
This has 2 consequences:
- LLDB cannot load the images before the process starts, reporting
an error if someone tries to break on a system symbol.
- Loading the symbols by downloading the data from the inferior
is super slow. It takes tens of seconds at the start of the
debug session to populate the Module list.
To fix this, we can use the library images LLDB has in its own
mapping of the shared cache. Shared cache images are somewhat
special as their LINKEDIT segment is moved to the end of the cache
and thus the images are not contiguous in memory. All of this can
hidden in ObjectFileMachO.
This patch fixes a number of test failures on macOS 11 due to the
first problem described above and adds some specific unittesting
for the new SharedCache Host utilities.
