5470e12c62 llvm-mc/x86: Fix various nit-picky bugs in displacement parsing.

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.

3fb7683bec Normalize SourceMgr messages.
- Don't print "Parsing" in front of every message.

 - Take additional "type" argument which is prepended to the message (with ": ")
   if given.

 - Update clients to print errors (warnings) as:
<filename>:<line number>: error(warning): ...
