LLVMgold.so tests are duplicated in several places. Deduplicate them.
Move the tests to lto.c and lto.cu
Specify -fuse-ld=bfd or -fuse-ld=gold.
In a future change, if -fuse-ld=lld or CLANG_DEFAULT_LINKER=lld without -fuse-ld=, we will remove -plugin /path/to/LLVMgold.so
There doesn't seem to be much sense in defaulting "on" unwind tables on
amd64 and not on other arches. It causes surprising differences between
platforms, such as the PR below[1].
Prior to this change, FreeBSD inherited the default implementation of the
method from the Gnu.h Generic_Elf => Generic_GCC parent class, which
returned true only for amd64 targets. Override that and opt on always,
similar to, e.g., NetBSD's driver.

FreeBSD's mips64 builds O32 binaries for /usr/lib32 by default and
thus needs to be able to link O32 binaries which requires an explicit
linker emulation. Go ahead and list all the linker emulation variants
for MIPS so that any supported MIPS ABI binary can be linked by any
linker supporting MIPS.

FreeBSD defaults to mips3 for all MIPS ABIs with GCC as that is the
minimum MIPS architecture FreeBSD supports. Use mips3 for MIPS64 and
mips2 for MIPS32 to match.

Summary:
FreeBSD N64 MIPS systems can include 32-bit libraries for O32 in
/usr/lib32 similar to the 32-bit compatibility libraries provided
for FreeBSD/amd64 and FreeBSD/powerpc64.

Summary:
Relanding https://reviews.llvm.org/D35739 which was reverted because
it broke the tests on non-Linux. The tests have been fixed to be
platform agnostic, and additional tests have been added to make sure
that the plugin has the correct extension on each platform
(%pluginext doesn't work in CHECK lines).

FreeBSD uses LLVM's libunwind on FreeBSD/arm64 today (and is expected to
use it more widely in the future), and it requires the EH frame segment
in static binaries.
This is the same as r203742 for NetBSD.

This currently changes the default toward the more historic -Av8/-Av9,
but as discussed with James Y Knight, consistency is for now more
important than figuring out which default CPU each OS should be using.

This is an experimental feature, where -integrated-as will be
on by default on ARM/Thumb. We aim to detect the missing features
so that the next release is stable.
Updating the ReleaseNotes, too.
Also moving the AArch64 into the same place.

clang itself. This dates back to clang's early days and while it looks like
some of it is still used (for kext for example), other parts are probably dead.
Remove the -ccc-clang-archs option and associated code. I don't think there
is any remaining setup where clang doesn't support an architecture but it can
expect an working gcc cross compiler to be available.
A nice side effect is that tests no longer need to differentiate architectures
that are included in production builds of clang and those that are not.

both actually tests what it wants to, doesn't have bogus and broken
assertions in it, and is also formatted much more cleanly and
consistently. Probably still some more that can be improved here, but
its much better.

Try to unbreak the FreeBSD toolchain's detection of 32-bit targets
inside a 64-bit freebsd machine with the 32-bit compatibility layer
installed. The FreeBSD image always has the /usr/lib32 directory, so
test for the more concrete existence of crt1.o. Also enhance the tests
for freebsd to clarify what these trees look like and exercise the new
code.
Thanks to all the FreeBSD folks for helping me understand what caused
the failure and how we might fix it. =] That helps a lot. Also, yay
build bots.

freebsd test so that it's behavior isn't dependent on the filesystem of
the host running the tests. This should revive the build bots at least.
The tests and the trees still need a lot of love to make them as useful
and easy to maintain as linux-ld.c.
