0b57cec536 Move all sources from the llvm project into contrib/llvm-project.
This uses the new layout of the upstream repository, which was recently
migrated to GitHub, and converted into a "monorepo".  That is, most of
the earlier separate sub-projects with their own branches and tags were
consolidated into one top-level directory, and are now branched and
tagged together.

Updating the vendor area to match this layout is next.

022d92870f When building libomp for i386, clang 9.0.0 produces a new warning about
large atomic operations "possibly incurring significant performance
penalties", but there is not much we can do about it, so squelch that
warning.

001ec17e68 To avoid unnecessarily modifying ports, add a -lgomp symlink, since GCC
does not ship a -lomp symlink.  Also update OptionalObsoleteFiles for
this, and add 32-bit variants while here.

e8067928ff Standardize -std=c++* as CXXSTD`
CXXSTD was added as the C++ analogue to CSTD.

CXXSTD defaults to `-std=c++11` with supporting compilers; `-std=gnu++98`,
otherwise for older versions of g++.

This change standardizes the CXXSTD variable, originally added to
googletest.test.inc.mk as part of r345203.

As part of this effort, convert all `CXXFLAGS+= -std=*` calls to use `CXXSTD`.

Notes:

This value is not sanity checked in bsd.sys.mk, however, given the two
most used C++ compilers on FreeBSD (clang++ and g++) support both modes, it is
likely to work with both toolchains. This method will be refined in the future
to support more variants of C++, as not all versions of clang++ and g++ (for
instance) support C++14, C++17, etc.

Any manual appending of `-std=*` to `CXXFLAGS` should be replaced with CXXSTD.
Example:

Before this commit:
```
CXXFLAGS+=	-std=c++14
```

After this commit:
```
CXXSTD=	c++14
```

bdbf3440ce Revert r345706: the third time will be the charm
When a review is closed via Phabricator it updates the patch attached to the
review. I downloaded the raw patch from Phabricator, applied it, and repeated
my mistake from r345704 by accident mixing content from D19732 and D19738.

For my own personal sanity, I will try not to mix reviews like this in the
future.

66110c6521 Remove --as-needed from the linker flags for libomp.so, as these
actually prevent the transitive dependency on libm.

db7591a848 Also explicitly link libomp.so against -lm, as it transitively depends
on scalbn and a few other math functions, via libcompiler-rt.  This
should allow OpenMP programs to link with BFD linkers too.

1d0078a2af Explicitly link libomp.so against -lpthread, as it depends on pthread
functionality.  This should make example OpenMP programs work out of the
box.

3c6bb67129 Add lib/libomp, with a Makefile, and generated configuration headers.
Not connected to the main build yet, as there is still the issue of the
GNU omp.h header conflicting with the LLVM one.  (That is, if MK_GCC is
enabled.)
