5bec168037 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): ...

5cf59dd842 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.

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.

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).

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.
