f97d8bbe73 implement a trivial binary expression parser, we can now parse all of 176.gcc.llc.s

1d1fe918de process memory operands with a parenthesized expression for a displacement, 
like "(4+5)(%eax)".

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).
