Brad Smith 70523ecfac [Sparc] Select the UltraSPARC instruction set with the external assembler 
Select the UltraSPARC instruction set with the external assembler on
Linux / FreeBSD / OpenBSD, matches GCC.

Fangrui Song b2b5cac3ec Default to -fuse-init-array 
Very few ELF platforms still use .ctors/.dtors now.  Linux (glibc: 1999-07),
DragonFlyBSD, FreeBSD (2012-03) and Solaris have supported .init_array
for many years. Some architectures like AArch64/RISC-V default to
.init_array . GNU ld and gold can even convert .ctors to .init_array .

It makes more sense to flip the CC1 default, and only uses
-fno-use-init-array on platforms that don't support .init_array .
For example, OpenBSD did not support DT_INIT_ARRAY before Aug 2016
(86fa57a279)

I may miss some ELF platforms that still use .ctors, but their
maintainers can easily diagnose such problems.

Joerg Sonnenberger 5c1ac90715 Use the generic Sparc CPU handling for Linux, FreeBSD and OpenBSD, too. 
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.

Dmitri Gribenko b9eb593e50 Correct OpenBSD profiling test 
The test should be looking for gcrt0.o not crt0.o.  Clang was already printing
"gcrt0", but the test was looking for "{{.*}}crt0.o", and the .* regexp
consumed "g".

Rafael Espindola fc3fc0c936 The clang driver has a fairly fancy support for executing gcc instead of 
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.
