a2701b4e72 Use string comparison instead of numeric comparison when comparing digests.

b34e3a9b6b whitespace cleanups, make the MipsAsmPrinter::doInitialization 
chain to the super class instead of initializing mangler directly.
This gives it .file and module level inline asm support among other
things.

d3ffc06174 fix Sparc, SystemZ, and MSP430 to not override AsmPrinter::doInitialization. 
This eliminates redundancy setting up the mangler and adds support to them
for module-level inline asm and a .file directive.

5d885023fe Another rewriter bug exposed by recent coalescer changes. ReuseInfo::GetRegForReload() should make sure the "switched" register is in the desired register class. I'm surprised this hasn't caused more failures in the past.
