H A Dspecialize.isa8250:de679a068dd8 Sat Apr 23 18:02:00 EDT 2011 Gabe Black <gblack@eecs.umich.edu> X86: When decoding a memory only inst, fault on reg encodings, don't assert.

This change makes the decoder figure out if an instruction that only supports
memory is using a register encoding and decodes directly to "Unknown" which will
behave appropriately. This prevents other parts of the instruction creation
process from seeing the mismatch and asserting.
