supporting other targets. Changed the code to pass MCAsmInfo to the parser
and the lexer. Then changed the lexer to use CommentString from MCAsmInfo
instead of a literal '#' character.

from MCAsmLexer.h in preparation of supporting other targets. Changed the
X86AsmParser code to reflect this by removing AsmLexer::LexPercent and looking
for AsmToken::Percent when parsing in places that used AsmToken::Register.
Then changed X86ATTAsmParser::ParseRegister to parse out registers as an
AsmToken::Percent followed by an AsmToken::Identifier.

instead of syntactically as a string. This means that it keeps track of the
segment, section, flags, etc directly and asmprints them in the right format.
This also includes parsing and validation support for llvm-mc and
"attribute(section)", so we should now start getting errors about invalid
section attributes from the compiler instead of the assembler on darwin.
Still todo:
1) Uniquing of darwin mcsections
2) Move all the Darwin stuff out to MCSectionMachO.[cpp|h]
3) there are a few FIXMEs, for example what is the syntax to get the
S_GB_ZEROFILL segment type?

- Yay for '-'s and simplifications!
- I kept StringMap::GetOrCreateValue for compatibility purposes, this can
eventually go away. Likewise the StringMapEntry Create functions still follow
the old style.
- NIFC.

- 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): ...

all of health and voronoi (ignoring directives). We only get 409 lines into
176.gcc though because we don't have binary operators yet:

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).
