Gabe Black cd8f604cc9 Seperate the pc-pc and the pc of the incoming bytes, and get rid of the "moreBytes" which just takes a MachInst. 
src/arch/x86/predecoder.cc:
    Seperate the pc-pc and the pc of the incoming bytes, and get rid of the "moreBytes" which just takes a MachInst. Also make the "opSize" field describe the number of bytes and not the log of the number of bytes.

Gabe Black 7860c045e2 x86 work that hadn't been checked in. 
src/arch/x86/isa/decoder/one_byte_opcodes.isa:
    Give the "MOV" instruction the format of it's arguments. This will likely need to be completely overhauled in the near future.
src/arch/x86/predecoder.cc:
src/arch/x86/predecoder.hh:
    Make the predecoder explicitly reset itself rather than counting on it happening naturally.
src/arch/x86/predecoder_tables.cc:
    Fix the immediate size table
src/arch/x86/regfile.cc:
    nextnpc is bogus

Gabe Black 75e8838ba4 Clean up the code a little, fix (I think) a perceived problem with immediate sizes, and sign extend the 32-bit-acting-like-64-bit-immediates.

Gabe Black 0a80d06dea Break out the one and two byte opcodes into different files. Also change what bits decode is done on to reflect where clumps of instructions are.

Gabe Black 075df1469f Added immediate value support, and fixed alot of bugs. This won't support 3 byte opcodes.
