Chris Lattner 3417d71ff4 refactor a bunch of X86 specific stuff out to its own file.

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

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

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 a7b51ed5e6 implement parser support for '*' operands, as in "call *%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.

Chris Lattner d485848229 oh yeah, cmake needs to be told explicitly about new files :)

Chris Lattner 8dd8a52533 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.
