As for other floating-point rounding builtins that can be optimized
when build with -fno-math-errno, this patch adds support for lround
and llround. It currently only optimize for AArch64 backend.

Buildbots complained that they couldn't find the newly added plugins.
The solution was to move the check-clang cmake target closer to the bottom of

Summary:
The definition of the builtins __builtin_bswap32, __builtin_bitreverse32, __builtin_rotateleft32 and __builtin_rotateright32 rely on that the int type is 32 bits wide on the target.
The defintions of the builtins __builtin_bswap64, __builtin_bitreverse64, __builtin_rotateleft64, and __builtin_rotateright64 rely on that the long long type is 64 bits wide.
On targets where this is not the case (e.g. AVR) clang will generate faulty code (wrong llvm assembler intrinsics).
This patch add support for using 'Z' (the int32_t type) in Bultins.def. The builtins above are changed to be based on the int32_t type instead of the int type, and the int64_t type instead of the long long type.
The AVR backend (experimental) have a native int type that is only 16 bits wide. The supplied testcase will therefore fail if running the testcase on trunk as clang will convert e.g. __builtin_bitreverse32 into llvm.bitreverse.i16 on AVR.

This reverts "r360833: [Clang][PP] Add the __FILE_NAME__ builtin macro."
The tests are failing on Windows bots, reverting the patchset until I can
work out why.
llvm-svn: 360842
This patch adds the `__FILE_NAME__` macro that expands to the
last component of the path, similar to `__FILE__` except with
a guarantee that only the last path component (without the
separator) will be rendered.
I intend to follow through with discussion of this with WG14
as a potential inclusion in the C standard or failing that,
try to discuss this with GCC developers since this extension
is desired by GCC and Clang users/developers alike.

(and less wrong).
It's not correct to assume that X<something, Type> is always a
template-id; there are a few cases where the comma takes us into a
non-expression syntactic context in which 'Type' might be permissible.
Stop doing that.
This slightly regresses our error recovery on the cases where the
construct is intended to be a template-id. We typically do still manage
to diagnose a missing 'template' keyword, but we realize this too late
to properly recover from the error.
This fixes a regression introduced by r360308.

Port hardware assisted address sanitizer to new PM following the same guidelines as msan and tsan.
Changes:
- Separate HWAddressSanitizer into a pass class and a sanitizer class.
- Create new PM wrapper pass for the sanitizer class.
- Use the getOrINsert pattern for some module level initialization declarations.
- Also enable kernel-kwasan in new PM
- Update llvm tests and add clang test.

I belive many of these diagnostics changed from errors to warnings in
r357394. I've simply mechanically updated the tests, but whoever owns
this code should probably audit for unintented behavior changes. I
wasn't able to find a flag to make these warnings errors again.

I think there must be a bug in git-llvm causing parent directories to be
deleted when the diff deletes files in a subdirectory. Perhaps it is
Windows-only.
There has been a behavior change, so some of these tests now fail. I
have marked them XFAIL and will fix them in a follow-up to separate the
changes.

evaluation.
This reinstates r360559, reverted in r360580, with a fix to avoid
crashing if evaluation-for-overflow mode encounters a virtual call on an
object of a class with a virtual base class, and to generally not try to
resolve virtual function calls to objects whose (notional) vptrs are not
readable. (The standard rules are unclear here, but this seems like a
reasonable approach.)

Currently `immintrin.h` includes `pconfigintrin.h` and `sgxintrin.h`
which contain inline assembly. It causes failures when building with the
flag `-fno-gnu-inline-asm`.
Fix by excluding functions with inline assembly when this extension is
disabled. So far there was no need to support `_pconfig_u32`,
`_enclu_u32`, `_encls_u32`, `_enclv_u32` on platforms that require
`-fno-gnu-inline-asm`. But if developers start using these functions,
they'll have compile-time undeclared identifier errors which is
preferrable to runtime errors.

This driver flag is useful when users want to link against the compiler's
builtins, but nothing else, and so use flags like -nostdlib.
Darwin can't use -nolibc & nostdlib++ like other platforms on because we
disable all runtime lib linking with -static, which we still want to have
an option to link with the builtins.

necessary.
Prior to r349952, clang used to call objc_msgSend when sending a release
messages, emitting an invoke instruction instead of a call instruction
when it was necessary to catch an exception. That changed in r349952
because runtime function objc_release is called as a nounwind function,
which broke programs that were overriding the dealloc method and
throwing an exception from it. This patch restores the behavior prior to
r349952.
