9a7e2ccf57 llvm-mc: Move AsmLexer::getCurStrVal to StringRef based API. 
- My DFS traversal of LLVM is, at least for now, nearly complete! :)

a5881e3060 Add TargetRegistry::lookupTarget. 
- This is a simplified mechanism which just looks up a target based on the
   target triple, with a few additional flags.

 - Remove getClosestStaticTargetForModule, the moral equivalent is now:
     lookupTarget(Mod->getTargetTriple, true, false, ...);

 - This no longer does the fuzzy matching with target data (based on endianness
   and pointer width) that getClosestStaticTargetForModule was doing, but this
   was deemed unnecessary.

6316fbcb04 Convert StringMap to using StringRef for its APIs. 
- Yay for '-'s and simplifications!

 - I kept StringMap::GetOrCreateValue for compatibility purposes, this can
   eventually go away. Likewise the StringMapEntry Create functions still follow
   the old style.

 - NIFC.

5026ae4514 Removed the DumpSymbolsandMacros and LoadSymbolsandMacros MCStreamer API as 
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.

2c3f00cd94 llvm-mc/x86: Fix bug in disambiguation of displacement operand, introduced by me 
(I think).
 - We weren't properly parsing the leading parenthesized expression in something
   like 'push (4)(%eax)'.
 
 - Added ParseParenRelocatableExpression to support this. I suspect we should
   just use lookahead, though.

 - Test case to follow.
