Ryan Houdek 0fc06c7bfa Implements an x86Table flag to partially ignore overlays 
Currently only support partially ignoring for overlay 0x66, this means
we only support no overlay at all and 0x66. Using only two bits of flag
space rather than 3.
If we find an instruction family that supports a different one then we
should break it out to three independent flags. Keeping it two until
then

Unit tests to ensure this keeps working is forthcoming

Ryan Houdek 65b85b2b4d Fixes bugs uncovered by the Group1 Primary table unit tests 
These instructions treat the immediate encoding differently depending on
the operating size of the instruction

For 16bit and 32bit operation they treat the immediate as an
appropriately sized immediate.
For 64bit operand size the immediate is sign extended to handle the new
operating width.
CMP was previously set to SEXT for this which would have its own set of
problems handling it like that.
