6f555ca2cd Delete MDNodes when LLVMContext is destroyed. Previous attempts: r97918, r97788. 
Tested: clang debug bootstrap, llvm-gcc bootstrap, `make check-lit`
after configuring with --with-llvmgccdir (and this did run the
FrontendC* tests this time)

815baebe1c Change ARM ld/st multiple instructions to have variant instructions for 
writebacks to the address register.  This gets rid of the hack that the
first register on the list was the magic writeback register operand.  There
was an implicit constraint that if that operand was not reg0 it had to match
the base register operand.  The post-RA scheduler's antidependency breaker
did not understand that constraint and sometimes changed one without the
other.  This also fixes Radar 7495976 and should help the verifier work
better for ARM code.

There are now new ld/st instructions explicit writeback operands and explicit
constraints that tie those registers together.

f08fde41f3 MC/Mach-O: Implement initial support for relaxation. 
- The implementation is currently very brain dead and inefficient, but I have a
   clear plan on how to fix it.

 - The good news is, it works and correctly assembles 403.gcc (when built with
   Clang, at '-Os', '-Os -g', and '-O3'). Even better, at '-Os' and '-Os -g',
   the resulting binary is exactly equivalent to that when built with the system
   assembler. So it probably works! :)
