chain to the super class instead of initializing mangler directly.
This gives it .file and module level inline asm support among other
things.

llvm-svn: 76593

This eliminates redundancy setting up the mangler and adds support to them
for module-level inline asm and a .file directive.

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.

Is this really a winning transformation?
fold (shl (srl x, c1), c2) -> (shl (and x, (shl -1, c1)), (sub c2, c1)) or

flags set properly.  (hasMemory is clearly irrelevant
when matching 'i', I don't understand what this was
supposed to be doing.)
