Add some scaffolding for a new experimental asmprinter
...
implementation. The idea is that we want asmprinting to
work by converting MachineInstrs into a new MCInst class,
then the per-instruction asmprinter works on MCInst. MCInst
and the new asmprinters will not depend on most of the
llvm code generators. This allows building diassemblers
that don't link in the whole llvm code generator. This is
step #1 of many.

Make changes to PCHReader to allow reading a PCH file without having a pre-initialized Preprocessor.
...
-Introduce 'PCHReaderListener' which is an abstract interface for getting various information from the PCHReader.
-If PCHReader is constructed without a Preprocessor, it can still load the file and invoke the callbacks of PCHReaderListener.
-If PCHReader is constructed with an initialized Preprocessor, PCHValidator is used as a PCHReaderListener to validate the contents of the PCH file against the given Preprocessor.
