Clang warns that a profile is out-of-date if it can't find a profile
record for any function in a TU. This warning became noisy after llvm
started allowing dead-stripping of instrumented functions.
To fix this, this patch changes the existing profile out-of-date warning
(-Wprofile-instr-out-of-date) so that it only complains about mismatched
data. Further, it introduces a new, off-by-default warning about missing
function data (-Wprofile-instr-missing).

Summary:
The type of the target frame index is intptr, not the type of the value we're
going to store into it. Without this change we crash in the attached test case
when trying to type-legalize a TargetFrameIndex.
Patchpoint lowering types the target frame index as intptr as well.

The UnknownPragmaHandlers added by DoPrintPreprocessedInput conflict with the
real PragmaHandlers from clang::Parser because they try to handle the same
#pragma directives. This makes it impossible to use a Preprocessor (that was
previously passed to DoPrintPreprocessedInput), as an Preprocessor for a
clang::Parser instance which is what we currently do in cling.
This patch removes the added UnknownPragmaHandler to avoid conflicts these
conflicts and leave the PragmaHandlers of the Preprocessors in a the same state
as before calling DoPrintPreprocessedInput.

libraries are properly unloaded when llvm_shutdown is called.
Summary:
This was mostly affecting usage of the JIT, where storing the library handles in
a set made iteration unordered/undefined. This lead to disagreement between the
JIT and native code as to what the address and implementation of particularly on
Windows with stdlib functions:
JIT: putenv_s("TEST", "VALUE") // called msvcrt.dll, putenv_s
JIT: getenv("TEST") -> "VALUE" // called msvcrt.dll, getenv
Native: getenv("TEST") -> NULL // called ucrt.dll, getenv
Also fixed is the issue of DynamicLibrary::getPermanentLibrary(0,0) on Windows
not giving priority to the process' symbols as it did on Unix.

This updates the regular expression used to match host/port pairs for the gdb-remote command to also match IPv6 addresses.
The IPv6 address matcher is very generic and does not really check for structural validity of the address. It turns out that IPv6 addresses are very complicated.

Polly comes in two library flavors: One loadable module to use the
LLVM framework -load mechanism, and another one that host applications
can link to. These have very different requirements for Polly's
own dependencies.
The loadable module assumes that all its LLVM dependencies are already
available in the address space of the host application, and is not allowed
to bring in its own copy of any LLVM library (including the NVPTX
backend in case of Polly-ACC).
The non-module library is intended to be linked to using
target_link_libraries. CMake would then resolve all of its dependencies,
including NVPTX and ensure that only a single instance of each library
will be used.

Previously parsing of these were all grouped together into a
single master class that could parse any type of debug info
fragment.
With writing forthcoming, the complexity of each individual
fragment is enough to warrant them having their own classes so
that reading and writing of each fragment type can be grouped
together, but isolated from the code for reading and writing
other fragment types.
In doing so, I found a place where parsing code was duplicated
for the FileChecksums fragment, across llvm-readobj and the
CodeView library, and one of the implementations had a bug.
Now that the codepaths are merged, the bug is resolved.

We have a lot of very similarly named classes related to
dealing with module debug info. This patch has NFC, it just
renames some classes to be more descriptive (albeit slightly
more to type). The mapping from old to new class names is as
follows:
Old | New
ModInfo | DbiModuleDescriptor
ModuleSubstream | ModuleDebugFragment
ModStream | ModuleDebugStream
With the corresponding Builder classes renamed accordingly.

Summary:
Previously, clang-format would accidentally parse an async function
declaration as a function expression, and thus not insert an unwrapped
line for async functions, causing subsequent functions to run into the
function:
async function f() {
x();
} function g() { ...
With this change, async functions get parsed as top level function
declarations and get their own unwrapped line context.

before r301492, we could specify "*:1234" as an address to lldb-server
and it would interpret that as "any". I am not sure that's a good idea,
but we have usages of that in the test suite, and without this the
remote test suite fails.
I'm adding that back, as it does not seem it was an intended side-effect
of that change, but I am open to removing it in the future, after
discussion and test suite fixup.

In getCmpSelInstrCost(), CondTy may actually be scalar while ValTy is a
vector when LoopVectorizer is the caller. Therefore the assert that CondTy
must be a vector type if ValTy is was wrong and is now removed.

for iOS < 9 and OS X < 10.11 X86 targets
This commit adds a new error that disallows methods that have parameters/return
values with a vector type for some older X86 targets. This diagnostic is
needed because objc_msgSend doesn't support SIMD vector registers/return values
on X86 in iOS < 9 and OS X < 10.11. Note that we don't necessarily know if the
vector argument/return value will use a SIMD register, so instead we chose to
be conservative and prohibit all vector types.

Fix a crash when trying to extend a value passed as a sign- or
zero-extended stack parameter. The cause of the crash was that we were
setting the size of the loaded value to 32 bits, and then tyring to
extend again to 32 bits.
This patch addresses the issue by also introducing a G_TRUNC after the
load. This will leave the unused bits to their original values set by
the caller, while being consistent about the types. For values that are
not extended, we just use a smaller load.

It is useful to output size of ranges when address ranges
section of .gdb_index is dumped.
It helps to compare outputs produced by different linkers,
for example. In that case address ranges can look very different,
when they are the same at fact. Difference comes from different
low address because of different address of .text.
