switch to this unconditionally. (& even if it weren't for that bug, one

As suggested by Richard Smith, and initially put up for review here:
https://reviews.llvm.org/D53341, this patch removes a hack that was used
to ensure that proper target-feature lists were used when emitting
cpu-dispatch (and eventually, target-clones) implementations. As a part
of this, the GlobalDecl object is proliferated to a bunch more
locations.
Originally, this was put up for review (see above) to get acceptance on
the approach, though discussion with Richard in San Diego showed he
approved of the approach taken here. Thus, I believe this is acceptable
for Review-After-commit

Summary:
clang currently uses llvm-config to determine the installation paths
for llvm's headers and binaries. clang is also using LLVM's cmake
files to determine other information about the LLVM build, like
LLVM_LIBDIR_SUFFIX, LLVM_VERSION_*, etc. Since the installation
paths are also available via the cmake files, we can simplify the code
by only relying on information from cmake about the LLVM install and
dropping the use of llvm-config altogether.
In addition to simplifying the code, the cmake files have more
accurate information about the llvm installation paths. llvm-config
assumes that the lib, bin, and cmake directories are always located
in the same place relative to the path of the llvm-config executable.
This can be wrong if a user decides to install headers, binaries
or libraries to a non-standard location: e.g. static libraries
installed to /usr/lib/llvm6.0/
This patch takes the first step towards dropping llvm-config by
removing the automatic detection of llvm-config (users can still
manually supply a path to llvm-config by passing
-DLLVM_CONFIG=/usr/bin/llvm-config to cmake) and adding a
deprecation warning when users try to use this option.

Summary:
When they read compiler args from compile_commands.json.
This change allows to run clang-based tools, like clang-tidy or clangd,
built from head using the compile_commands.json file produced for XCode
toolchains.
On MacOS clang can find the C++ standard library relative to the
compiler installation dir.
The logic to do this was based on resource dir as an approximation of
where the compiler is installed. This broke the tools that read
'compile_commands.json' and don't ship with the compiler, as they
typically change resource dir.
To workaround this, we now use compiler install dir detected by the driver
to better mimic the behavior of the original compiler when replaying the
compilations using other tools.

FunctionDecl::Create() takes as its T parameter the type of function

usages outweighs the incorrect ones so I've opted for keeping what T is
the same and fixing up the call sites instead.

When we cast a function pointer to an int pointer, at some pointer later
it gets bitcasted back to a function and called.
In backends that have a nonzero program memory address space specified
in the data layout, the old code would lose the address space data. When
LLVM later attempted to generate the bitcast from i8* to i8(..)*
addrspace(1), it would fail because the pointers are not in the same
address space.
With this patch, the address space of the function will carry on to the
address space of the i8* pointer. This is because all function pointers
in Harvard architectures need to be assigned to the correct address
space.
This has no effect to any in-tree backends except AVR.

Currently, we only accept clang as the scoped attribute identifier for double square bracket attributes provided by Clang, but this has the potential to conflict with user-defined macros.

The clang-cl driver disables access to command line options outside of the
"Core" and "CLOption" sets of command line arguments. This filtering makes it
impossible to pass arguments that are interpreted by the clang driver and not
by either 'cc1' (the frontend) or one of the other tools invoked by the driver.
An example driver-level flag is the '-fno-slp-vectorize' flag, which is
processed by the driver in Clang::ConstructJob and used to set the cc1 flag
"-vectorize-slp". There is no negative cc1 flag or -mllvm flag, so it is not
currently possible to disable the SLP vectorizer from the clang-cl driver.
This change introduces the "/clang:" argument that is available when the
driver mode is set to CL compatibility. This option works similarly to the
"-Xclang" option, except that the option values are processed by the clang
driver rather than by 'cc1'. An example usage is:
clang-cl /clang:-fno-slp-vectorize /O2 test.c
Another example shows how "/clang:" can be used to pass a flag where there is
a conflict between a clang-cl compat option and an overlapping clang driver
option:
clang-cl /MD /clang:-MD /clang:-MF /clang:test_dep_file.dep test.c
In the previous example, the unprefixed /MD selects the DLL version of the msvc
CRT, while the prefixed -MD flag and the -MF flags are used to create a make
dependency file for included headers.
One note about flag ordering: the /clang: flags are concatenated to the end of
the argument list, so in cases where the last flag wins, the /clang: flags
will be chosen regardless of their order relative to other flags on the driver
command line.

Summary:
Previously the TemplateSpecialization instance for 'template_alias', in the example below, returned the type info of the canonical type (int). This ignored the type alias if the template type happen to be aliased.
Before this patch, the assert would trigger with an alignment of 4:
```
typedef int __attribute__(( aligned( 16 ) )) aligned_int;
template < typename >
using template_alias = aligned_int;
static_assert( alignof( template_alias<void>) == 16, "" );
```
This patch checks if the TemplateSpecialization type has an alias, and if so will return the type information for the aliased type, else the canonical type's info is returned (original behavior). I believe that this is the desired behavior.

proposing to restrict AnalyzerOptions' interface so that only checker options
can be retrieved without special getters. I would like to make every option be
accessible only through a getter, but checkers from plugins are a thing, so I'll
have to figure something out for that.
This also forces developers who'd like to add a new option to register it
properly in the .def file.
This is done by
* making the third checker pointer parameter non-optional, and checked by an
assert to be non-null.
* I added new, but private non-checkers option initializers, meant only for
internal use,
* Renamed these methods accordingly (mind the consistent name for once with
getBooleanOption!):
- getOptionAsString -> getCheckerStringOption,
- getOptionAsInteger -> getCheckerIntegerOption
* The 3 functions meant for initializing data members (with the not very
descriptive getBooleanOption, getOptionAsString and getOptionAsUInt names)
were renamed to be overloads of the getAndInitOption function name.
* All options were in some way retrieved via getCheckerOption. I removed it, and
moved the logic to getStringOption and getCheckerStringOption. This did cause
some code duplication, but that's the only way I could do it, now that checker
and non-checker options are separated. Note that the non-checker version
inserts the new option to the ConfigTable with the default value, but the
checker version only attempts to find already existing entries. This is how
it always worked, but this is clunky and I might end reworking that too, so we
can eventually get a ConfigTable that contains the entire configuration of the
analyzer.

Windows buildbots break with the previous commit '[analyzer][PlistMacroExpansion]
Part 2.: Retrieving the macro name and primitive expansion'. This patch attempts
to solve this issue.

-static relies on lld's behavior, but -Bstatic/dynamic is supported
across all linkers.
