The above builtins are currently implemented for MSVC mode, however GCC
also implements these. This patch enables them for all platforms.
Additionally, this corrects the type for these builtins to always be
'long int' to match the specification in the Intel Intrinsics Guide.

On SPIR targets, the default calling convention is SpirFunction.
However, operator new/delete and builtins were being created with CC_C.
The result is indirect references to new/delete (or builtins that are permitted
to be called indirectly have a mismatched type, as well as questionable codegen
in some cases.
This patch sets both to the default calling convention, so that it
properly matches the calling convention of the target.

Under the term "subchecker", I mean checkers that do not have a checker class on
their own, like unix.MallocChecker to unix.DynamicMemoryModeling.
Since a checker object was required in order to retrieve checker options,
subcheckers couldn't possess options on their own.
This patch is also an excuse to change the argument order of getChecker*Option,
it always bothered me, now it resembles the actual command line argument
(checkername:option=value).

Support locating the libc++ header files relatively to the clang
executable, in addition to the default system path. This is meant
to cover two use cases: running just-built clang from the install
directory, and running installed clang from non-standard location
(e.g. /usr/local).
This is the first step towards ensuring that tests of more LLVM projects
can work out-of-the-box within the build tree, and use the correct set
of headers (rather than e.g. mixing just-built clang+libcxx with system
install of libcxx). It avoids requiring the user to hack around missing
include paths, or LLVM build system to replicate system-specific C++
library defaults in order to append appropriate paths implicitly.

Then, as a consequence, remove the complex set of workarounds for
initialization order -- which are apparently not 100% reliable.
The only downside is that some of the member functions are now
specific to kNumElem == 2, and will need to be updated if that
constant is increased in the future.
Unfortunately, the current code caused an initialization-order runtime
failure for me in some compilation modes. It appears that in a
toolchain without init-array enabled, the order of initialization of
static data members of a template can be reversed w.r.t. the order
within a file.
This caused e.g. SanitizerKind::CFI to be initialized to 0.
I'm not quite sure if that is an allowable ordering variation, or
nonconforming behavior, but in any case, making everything constexpr
eliminates the possibility of such an issue.

This clean up should also make future modifications easier, like

When emitting initializers for local structures for code built with
-ftrivial-auto-var-init, replace constant structures with sequences of
stores.
This appears to greatly help removing dead initialization stores to those
locals that are later overwritten by other data.
This also removes a lot of .rodata constants (see PR40605), replacing most
of them with immediate values (for Linux kernel the .rodata size is
reduced by ~1.9%)

When we have an annotated local variable after a function returns, we
generate IR that fails verification with the error

And it means that bitcast referencing alloca doesn't have a parent basic
block.
Fix by checking if we are at an unreachable point and skip emitting
annotations. This approach is similar to the way we emit variable
initializer and debug info.

Summary:
clang-formatting wants to add spaces around items in square braces, e.g. [1, 2] -> [ 1, 2 ]. Based on a quick check [1], it seems like most cases are using the [1, 2] format, so make that the consistent one.
[1] in llvm `.td` files, the regex `\[[^ ]` (bracket followed by not-a-space) shows up ~400 times, but `\[\s[^ ]` (bracket followed by one space and one not-a-space) shows up ~40 times => ~90% uses this format.

Summary:
In the clang UI, replaces -mthread-model posix with -matomics as the
source of truth on threading. In the backend, replaces
-thread-model=posix with the atomics target feature, which is now
collected on the WebAssemblyTargetMachine along with all other used
features. These collected features will also be used to emit the
target features section in the future.
The default configuration for the backend is thread-model=posix and no
atomics, which was previously an invalid configuration. This change
makes the default valid because the thread model is ignored.
A side effect of this change is that objects are never emitted with
passive segments. It will instead be up to the linker to decide
whether sections should be active or passive based on whether atomics
are used in the final link.

Summary:
I hadn't realized that instrumentation runs before inlining, so we can't
use the function as the comdat group. Doing so can create relocations
against discarded sections when references to discarded __profc_
variables are inlined into functions outside the function's comdat
group.
In the future, perhaps we should consider standardizing the comdat group
names that ELF and COFF use. It will save object file size, since
__profv_$sym won't appear in the symbol table again.

Summary:
This allows ASTs to be merged when they contain ChooseExpr (the GNU
__builtin_choose_expr construction). This is needed, for example, for
cross-CTU analysis of C code that makes use of __builtin_choose_expr.
The node is already supported in the AST, but it didn't have a matcher
in ASTMatchers. So, this change adds the matcher and adds support to
ASTImporter.
This was originally reviewed and approved in
https://reviews.llvm.org/D58292 and submitted as r354832. It was
reverted in r354839 due to failures on the Windows CI builds.
This version fixes the test failures on Windows, which were caused by
differences in template expansion between versions of clang on different
OSes. The version of clang built with MSVC and running on Windows never
expands the template in the C++ test in ImportExpr.ImportChooseExpr in
clang/unittests/AST/ASTImporter.cpp, but the version on Linux does for
the empty arguments and -fms-compatibility.
So, this version of the patch drops the C++ test for
__builtin_choose_expr, since that version was written to catch
regressions of the logic for isConditionTrue() in the AST import code
for ChooseExpr, and those regressions are also caught by
ASTImporterOptionSpecificTestBase.ImportChooseExpr, which does work on
Windows.
