da759cfa32 Remove -mlong-calls vhen building arm libraries and llvm.
Clang from 9.0.0 onwards already has the necessary relocation range
extenders, so this workaround is no longer needed (it produces longer
and slower code). Tested on real hardware, and in cross-compile
environment.

arichardson has an actual fix for the same issue that this was working
around; given that we don't build with llvm today, go ahead and revert the
workaround in advance.

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.

036d2e814b Re-add ALLOW_MIPS_SHARED_TEXTREL, sprinkle it around
Diff partially stolen from CheriBSD; these bits need -Wl,-z,notext in order
to build in an LLVM world. They are needed for all flavors/sizes of MIPS.
This will eventually get fixed in LLVM, but it's unclear when.

1109b77451 Rework CXXSTD setting via r345708
This change allows the user to once again override the C++ standard, restoring
high-level pre-r345708 behavior.

This also unbreaks building lib/ofed/libibnetdisc/Makefile with a non-C++11
capable compiler, e.g., g++ 4.2.1, as the library supported being built with
older C++ standards.

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.

ce00342bb2 Move external GCC compiler hacks to bsd.sys.mk.
This allows respecting -nostdinc, -nostdinc++ and -nostdlib before
making the decision to add in -isystem, etc.  The -isystem flags
are problematic for building lib/libc++ and lib/libcxxrt which wants
to only use its own headers.

More information the need of these flags can be found at
https://gcc.gnu.org/ml/gcc/2016-03/msg00219.html

This also reverts r300873.

09210a281c After r300770, for libc++ and libcxxrt, use -isystem instead of -I.
This should fix builds with external gcc toolchains from ports, which
also use -isystem to work around problems with gcc's --sysroot
implementation.  Thanks to Bryan Drewery for this workaround.
