7d145b44cc lib/Target/X86/X86TargetMachine.{cpp,h}: Add initial version 
(non-working) of llc guts for X86, and add a prototype for it.

013ad21206 Implement code to keep the stack pointer aligned to an 8 byte boundary. 
This improves the performance of the power benchmark by a few percent.
This will be neccesary for SSE code, which requires 16 byte alignment of
the stack.
