ac0f5e081e 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.

433fbf959a 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.

ed8c3ea053 convert this test to filecheck format, which is faster and avoids false matches of "st" -> "stdin"

c142755cec 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.

0cf19155ef Fix a dagga combiner bug: avoid creating illegal constant. 
Is this really a winning transformation?
fold (shl (srl x, c1), c2) -> (shl (and x, (shl -1, c1)), (sub c2, c1)) or

by determining if (B pred (B-A)) is known, as it doesn't handle
overflow correctly.

ee3f2d6dc3 Make sure a global matching asm 'i' constraint gets its 
flags set properly.  (hasMemory is clearly irrelevant
when matching 'i', I don't understand what this was
supposed to be doing.)
gcc.apple/asm-block-25.c (test passed before by
accident, but generated code was wrong)

16a69eeaeb Pass in the unfortunately named "LessPrivatePrefix" for the 
"LinkerPrivatePrefix". It seems to have been used in only one place before I
started this "linker_private" business. I'm thinking that a rename is in
order...
