Remove unused field from FixedLenDecoderEmitter. Move NumberedInstructions declaration from class to run method since its only used there and was being reinitialized anyway.

Allow the MCDisassembler to return a "soft fail" status code, indicating an instruction that is disassemblable, but invalid. Only used for ARM UNPREDICTABLE instructions at the moment.

Add FixedLenDecoderEmitter, the skeleton of a new disassembler emitter for fixed-length instruction encodings.
...
A major part of its (eventual) goal is to support a much cleaner separation between disassembly callbacks
provided by the target and the disassembler emitter itself, i.e. not requiring hardcoding of knowledge in tblgen
like the existing disassembly emitters do.
The hope is that some day this will allow us to replace the existing non-Thumb ARM disassembler and remove
some of the hacks the old one introduced to tblgen.
