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): ...

Chris Lattner 4c501fc196 make the lexer unique strings it lexes instead of passing them back as 
std::strings.

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
	      	         ^

Chris Lattner 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).

Chris Lattner d0765617d2 implement enough of a lexer to get through Olden/health/Output/health.llc.s 
without errors.
