dd611ca434 Revert 76080. This broke some powerpc cross compiles. 
It also makes the llvmCore build dependent on whatever version of llvm-gcc
happens to be installed on the build machine.

Add a testcase.

e30a44267c llvm-mc/Mach-O: Add MCCodeEmitter support, for encoding instructions.

9a8ec155f7 llvm-mc/X86: Implement single instruction encoding interface for MC. 
- Note, this is a gigantic hack, with the sole purpose of unblocking further
   work on the assembler (its also possible to test the mathcer more completely
   now).

 - Despite being a hack, its actually good enough to work over all of 403.gcc
   (although some encodings are probably incorrect). This is a testament to the 
   beauty of X86's MachineInstr, no doubt! ;)

7785b6000e Implement a new optimization in the inliner: if inlining multiple 
calls into a function and if the calls bring in arrays, try to merge
them together to reduce stack size.  For example, in the testcase
we'd previously end up with 4 allocas, now we end up with 2 allocas.

As described in the comments, this is not really the ideal solution
to this problem, but it is surprisingly effective.  For example, on
176.gcc, we end up eliminating 67 arrays at "gccas" time and another
24 at "llvm-ld" time.

One piece of concern that I didn't look into: at -O0 -g with
forced inlining this will almost certainly result in worse debug
info.  I think this is acceptable though given that this is a case
of "debugging optimized code", and we don't want debug info to
prevent the optimizer from doing things anyway.
