4f3e7aa154 add a helper method for creating MCSymbol and MCSymbolRefExpr at 
the same time.

bfd1e50c4f remove some horrible MAI hooks which fortunately turn out to be always empty.

90edac0e8b Change MCAsmStreamer to take an MCInstPrinter instead of a 
full AsmPrinter, and change TargetRegistry to keep track
of registered MCInstPrinters.

llvm-mc is still linking in the entire
target foo to get the code emitter stuff, but this is an
important step in the right direction.

b6a2fc080f eliminate the "MBBLabel" MCOperand type, and just use a MCSymbol for 
MBB labels like everything else.

c5ea263a23 remove DebugLoc from MCInst and eliminate "Comment printing" from 
the MCInst path of the asmprinter.  Instead, pull comment printing
out of the autogenerated asmprinter into each target that uses the
autogenerated asmprinter.  This causes code duplication into each
target, but in a way that will be easier to clean up later when more
asmprinter stuff is commonized into the base AsmPrinter class.

This also fixes an xcore strangeness where it inserted two tabs
before every instruction.

251ef612a8 Added an abstract superclass, MCDisassembler, for 
all disassemblers.

Modified the MemoryObject to support 64-bit address
spaces, regardless of the LLVM process's address
width.

Modified the Target class to allow extraction of a
MCDisassembler.

new asmprinter.  Differently gross hack coming next.

fb0f0dedd7 Added AsmToken enum constants to MCAsmLexer.h for '[', ']', '{', and '}' in 
preparation of supporting other targets. Then changed the lexer to parse these
as tokens.

9823ca971d Added the AsmToken::Hash enum constant to MCAsmLexer.h in preparation of 
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.

7b4608dfa0 Removed the non-target independent AsmToken::Register enum constant 
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.

functionality change other than unbreaking my previous patch.
