REPNE on MOVS is unsupported, most likely the prefix is ignored but
until a hardware test can confirm update the comment

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

Fixes BSR and BSF 32bit op when source is zero

BSR/BSF needs to not write to destination when source is zero
This ensures it doesn't clear the upper 32bits of the register in this
case.

Fixes translation of a 16bit CALL instruction
...
This instruction is effectively dead since Linux reserves the lower
16bits for itself, but in the case that someone manages to encode it
then we will at least attempt to access the correct RIP.

Fixes a bug in PUSH that unit tests uncovered
...
In an edge cases of pushing with a 32bit immediate sign extended to
64bit then there could have been a conflict.
Rearrange the ordering a bit to ensure it is correct

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.
