79ed1a8734 Added a Lex function to the AsmParser, to allow handling
of include directives to occur within the parser itself.
This will break the lexer's dependency on a SourceMgr as
input.

9898671a74 Split the TargetAsmParser "ParseInstruction" interface in half:
the new ParseInstruction method just parses and returns a list of
target operands.  A new MatchInstruction interface is used to
turn the operand list into an MCInst.

This requires new/deleting all the operands, but it also gives 
targets the ability to use polymorphic operands if they want to.

ba847da571 Test harness for the LLVM disassembler. When invoked

the chosen (or default) target, printing the result.

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.

out of AsmParser.cpp into X86AsmParser.cpp as it is 2 bytes on X86 and 4 bytes
for other targets that support the .word directive.

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.
