Properly encapsulate additional methods and data from AsmParser.

This finally allows AsmParser to no longer list GenericAsmParser as a friend.
All member vars directly accessed by GenericAsmParser have been properly
encapsulated and exposed through the MCAsmParser interface. This reduces the
coupling between AsmParser and GenericAsmParser.

Now GenericAsmParser and AsmParser are no longer friends, GenericAsmParser can
simply use the getParser method from MCAsmParserExtension, working through the
MCAsmParser interface. There's no longer a need to overload that method to
cast it to the concrete AsmParser.
