0945d20ceb add support for parsing and emitting .section directives. We can now parse 
things like:
.section __TEXT,__cstring,cstring_literals

61a6509f6a 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.

d3b90f1344 make the lexer unique strings it lexes instead of passing them back as 
std::strings.

43a2dca0e4 implement a trivial binary expression parser, we can now parse all of 176.gcc.llc.s

886ab50a50 process memory operands with a parenthesized expression for a displacement, 
like "(4+5)(%eax)".

5927443800 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
	      	         ^

89e17d02b1 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).

b6cfcfadd4 implement enough of a lexer to get through Olden/health/Output/health.llc.s 
without errors.

698abf1ad4 Add a skeleton driver for new machine code level fun. llvm-mc is meant 
to be a test driver of other components in the system, which will develop
over time.
