Daniel Dunbar 0224b65f0a llvm-mc/x86: Fix various nit-picky bugs in displacement parsing.
- Test case to follow.

Daniel Dunbar 9bff6531fd 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.

Daniel Dunbar 8561b6aea0 llvm-mc: Symbols in a relocatable expression of the (a - b + cst) form are
allowed to be undefined when the expression is seen, we cannot enforce the
same-section requirement until the entire assembly file has been seen.

Daniel Dunbar c9dc78ae40 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): ...

Daniel Dunbar ae7ac01059 llvm-mc: Diagnose misuse (mix) of defined symbols and labels.
- For example, we diagnose errors on:
--
a:
a = 10
--

 - For now we reject code like:
--
.long a
a = 10
--
   which "as" accepts (on Darwin).

Chris Lattner 7fdbce7a60 Implement full support for parsing primary expressions. We can now parse
all of health and voronoi (ignoring directives).  We only get 409 lines into
176.gcc though because we don't have binary operators yet:

Parsing 176.gcc.llc.s:409: unexpected token in operand list
	movsbl	_arityvec+1(,%edi,8), %eax
	      	         ^
