Upgrade libcompiler_rt from revision 117047 to 132478.

Browse Source 
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.
