Dimitry Andric f8099f256d Add more gcc compatibility names to clang's cpuid.h
Summary:
Some cpuid bit defines are named slightly different from how gcc's
cpuid.h calls them.

Define a few more compatibility names to appease software built for gcc:

* `bit_PCLMUL`      alias of `bit_PCLMULQDQ`
* `bit_SSE4_1`      alias of `bit_SSE41`
* `bit_SSE4_2`      alias of `bit_SSE42`
* `bit_AES`         alias of `bit_AESNI`
* `bit_CMPXCHG8B`   alias of `bit_CX8`

While here, add the misssing 29th bit, `bit_F16C` (which is how gcc
calls this bit).

Dimitry Andric 75534e23d0 XFAIL one sanitizer symbolizer test for FreeBSD
Summary:
Due to a QoI issuse in FreeBSD's libcxxrt-based demangler, one sanitizer
symbolizer test consistently appears to fail:

    Value of: DemangleSwiftAndCXX("foo")
      Actual: "float"
    Expected: "foo"

This is because libcxxrt's __cxa_demangle() incorrectly demangles the "foo"
identifier to "float".  It should return an error instead.

For now, XFAIL this particular test for FreeBSD, until we can fix libcxxrt
properly (which might take some time to coordinate with upstream).

Etienne Bergeron 0b2d71373b [compiler-rt] Add support for interception redirect exports.
Summary:
On windows, an export can be redirected to an other DLL.
This patch is adding the required support to the internal
GetProcAddress implementation.

This case was encountered by instrumenting chromium (win 64-bits)
using this GN configuration:
```
is_component_build = true
is_debug = false
enable_nacl = false
is_clang = true
is_asan = true
clang_base_path = "d:\src\llvm\ninja64"
clang_use_chrome_plugins = false
clang_version = "4.0.0"
```

The operating system is win7 (x64).
Visual Studio: 2015 Professional

Hubert Tong 01a2cb55f1 TrailingObjects::FixedSizeStorage constexpr fixes + tests
Summary:
This change fixes issues with `LLVM_CONSTEXPR` functions and
`TrailingObjects::FixedSizeStorage`. In particular, some of the
functions marked `LLVM_CONSTEXPR` used by `FixedSizeStorage` were not
implemented such that they evaluate successfully as part of a constant
expression despite constant arguments.

This change also implements a more traditional template-meta path to
accommodate MSVC, and adds unit tests for `FixedSizeStorage`.

Drive-by fix: the access control for members of `TrailingObjectsImpl` is
tightened.

Hubert Tong a216643cd3 MathExtras.h: add LLVM_CONSTEXPR where simple
Summary:
This change adds `LLVM_CONSTEXPR` to functions selected as follows:
- the body is already valid under C++11 for a `constexpr` function,
- the evaluation of the function, given constant arguments, will not
  fail during the evaluation of a constant expression, and
- the above properties are easily verifiable at a glance.

Note: the evaluation of the function cannot fail if the instantiation
triggers a static assertion failure.

Extend the jscop interface to allow the user to export arrays. It is required

of the SCoP. Each array that is appended to the list will be newly created.
Furthermore, we allow the user to modify access expressions to reference
any array in case it has the same element type.
