ee01b242e8 Factor commonality in triple match routines into helper template for registering
classes, and migrate existing targets over.

47d679151b Add TargetRegistry::lookupTarget.
- This is a simplified mechanism which just looks up a target based on the
   target triple, with a few additional flags.

 - Remove getClosestStaticTargetForModule, the moral equivalent is now:
     lookupTarget(Mod->getTargetTriple, true, false, ...);

 - This no longer does the fuzzy matching with target data (based on endianness
   and pointer width) that getClosestStaticTargetForModule was doing, but this
   was deemed unnecessary.

3c2a893ac7 Add MCAsmParser interface.
- This provides the AsmParser interface to the target specific assembly
   parsers.

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): ...

a10e519e04 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.

3f5738d599 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.

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).

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.
