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

when matching 'i', I don't understand what this was
supposed to be doing.)

as it no longer depends upon two different enums being kept in sync with each

the parsing of the .dump and .load should be done in the assembly parser and
not have any need for an MCStreamer API.  Changed the code for now so these
just produce an error saying these specific directives are not yet implemented
since they are likely no longer used and may never need to be implemented.

 - This provides the AsmLexer interface to the target specific assembly parsers.
