Fixes bug in 64bit def mod instructions that are in 16bit mode
...
These would have been forced to 64bit when they would have wanted to be
operating in 16bit mode.
Fixes that.

Changes to the new multiblock frontend decoder
...
Simple linear scan forward of instruction decoding isn't viable to do.
We need to break up the decoding at the block boundaries.
Otherwise our decoding gets in to the weeds and decodes trash.

Results in a decent performance increase by itself.

Flesh out X86Tables some more
...
Adds an EVEX table and throws some ops in to an unimplemented function.
This is necessary for multiblock in the future where it will see
unsupported instructions but not actually execute them.
