Fixes the following:
  BOOL (^aaa)(void) = ^BOOL {
  };

The first BOOL's token was getting set to TT_FunctionAnnotationRParen
incorrectly, which was causing an unexpected newline after (^aaa). This
was introduced in r245846.

On ARM, there are multiple versions of each of the intrinsics, with
acquire/relaxed/release barrier semantics.

The newly added ones are provided as inline functions here instead of builtins,
since they should only be available on certain archs (arm/aarch64).

This is necessary in order to compile C++ code for ARM in MSVC mode.

Summary:
Currently, a linker option must be used to control the backend
parallelism of ThinLTO. The linker option varies depending on the
linker (e.g. gold vs ld64). Add a new clang option -flto-jobs=N
to control this.

I've added in the wiring to pass this to the gold plugin. I also
added in the logic to pass this down in the form I understand that
ld64 uses on MacOS, for the darwin target.

Clang has the default FP contraction setting of “-ffp-contract=on”, which
doesn't really mean “on” in the conventional sense of the word, but rather
really means “according to the per-statement effective value of the relevant
pragma”.

Before this patch, Clang has that pragma defaulting to “off”. Since the
“-ffp-contract=on” mode is really an AND of two booleans and the second of them
defaults to “off”, the whole thing effectively defaults to “off”. This patch
changes the default value of the pragma to “on”, thus making the default pair of
booleans (on, on) rather than (on, off). This makes FP optimization slightly
more aggressive than before when not using either “-Ofast”, “-ffast-math”, or
“-ffp-contract=fast”. Even with this patch the compiler still respects
“-ffp-contract=off”.

As per a suggestion by Steve Canon, the added code does _not_ require “-O3” or
higher. This is so as to try our best to preserve identical floating-point
results for unchanged source code compiling for an unchanged target when only
changing from any optimization level in the set (“-O0”, “-O1”, “-O2”, “-O3”) to
any other optimization level in that set. “-Os” and “-Oz” seem to be behaving
identically, i.e. should probably be considered a part of the aforementioned
set, but I have not reviewed this rigorously. “-Ofast” is explicitly _not_ a
member of that set.

Summary:
The ASAN unittests are failing (check-asan-dynamic) due to an incorrect symbol name:
```
LINK : error LNK2001: unresolved external symbol ___asan_seh_interceptor

On win64, the linker is not adding an extra underscore. This was correctly fixed in the same file for other uses.

After that patch, most of the unittests are passing, but some related to SEH needs to be fixed.

The backend can't encode all possible values of the argument and will fail isel. Checking in the frontend presents a friendlier experience to the user.

Like NetBSD, OpenBSD prefers having a consistent set of typedefs
across the architectures it supports over strictly following the ARM
ABIs.  The diff below makes sure that clang's view of those types
matches OpenBSD's system header files.  It also adds a test that
checks the relevant types on all OpenBSD platforms that clang works
on.  Hopefully we can add mips64 and powerpc to that list in the
future.
