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.

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): ...

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).

a10e519e04 Basic .s parsing for .asci[iz], .fill, .space, {.byte, .short, ... } 
- Includes some DG tests in test/MC/AsmParser, which are rather primitive since
   we don't have a -verify mode yet.

3f5738d599 add trivial support for passing label definitions through the MCStreamer. 
This is suboptimal in several aspects, see the commented out assertion.
I need to talk to Daniel about this.

std::strings.

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
	      	         ^

b013345338 stub out parser for asm files. Change invariant on lexer to always 
print its error message when it returns an asmtok::Error token.
Compute a proper error code for llvm-mc in 'lex' mode.  Add new
-as-lex option to enable lexing mode (vs parsing mode).
