f8ca070d3a Merge compiler-rt release_38 branch r258968.
Note that there is still a problem on amd64, causing SIGBUS in the early
startup of Address Sanitizer.  This is being investigated.

57eba68124 compiler-rt: update __multc3 to upstream style and variable names
I introduced a local copy of __multc3 in r281221, which has now been
committed upstream to compiler-rt in revision 245296. Update our version
to match the changes made there.

This is mostly a no-op other than for ARM where it adds missing
__aeabi_mem* and __aeabi_*divmod functions. Even on ARM these will remain
unused until the rest of the ARM EABI code is merged.

2040613422 - Get rid of debugging support in order to get rid of the V8-specific C
compiler frame size used there so this whole thing is V8/V9-agnostic.
- Use 32-bit function alignment as GCC does when using UltraSPARC I or
  higher optimizations.
- Don't waste delay slots when possible.

Unfortunately, this still doesn't make libcompiler_rt a viable replacement
for libgcc on sparc64 though as once installed instead, buildworld times
increase by nearly 60% (which isn't related to these assembler functions).

a8c104fbb0 Add a workaround to prevent endless recursion in compiler-rt.
SPARC and MIPS CPUs don't have special instructions to count
leading/trailing zeroes. The compiler-rt library provides fallback
rountines for these. The 64-bit routines, __clzdi2 and __ctzdi2, are
implemented as simple wrappers around the compiler built-in
__builtin_clz(), assuming these will expand to either 32-bit
CPU instructions or calls to __clzsi2 and __ctzsi2.

Unfortunately, our GCC 4.2 probably thinks that because the operand is
stored in a 64-bit register, it might just be a better idea to invoke
its 64-bit equivalent, simply resulting into endless recursion. Fix this
by defining __builtin_clz and __builtin_ctz to __clzsi2 and __ctzsi2
explicitly.

7686ff743c Upgrade libcompiler_rt to upstream revision 147390.
This version of libcompiler_rt adds support for __mulo[sdt]i4(), which
computes a multiply and its overflow flag. There are also a lot of
cleanup fixes to headers that don't really affect us.

Updating to this revision should make it a bit easier to contribute
changes back to the LLVM developers.

ef8821e5db Upgrade libcompiler_rt from revision 117047 to 132478.
It seems there have only been a small amount to the compiler-rt source
code in the mean time. I'd rather have the code in sync as much as
possible by the time we release 9.0. Changes:

- The libcompiler_rt library is now dual licensed under both the
  University of Illinois "BSD-Like" license and the MIT license.

- Our local modifications for using .hidden instead of .private_extern
  have been upstreamed, meaning our changes to lib/assembly.h can now be
  reverted.

- A possible endless recursion in __modsi3() has been fixed.

- Support for ARM EABI has been added, but it has no effect on FreeBSD
  (yet).

- The functions __udivmodsi4 and __divmodsi4 have been added.

Not doing so may cause all sorts of random libraries to expose
