Ryan Houdek e1cecbcfe3 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.

Ryan Houdek 5db8de625a Adds a few new instructions to the X86Tables 
I managed to hit these when messing with Multiblock.

Ryan Houdek fc8c6c80fb Makes sure in Frontend we say that Entry and ConditionalJump fallthroughs are JumpTargets 2020-03-06 07:55:37 +02:00
Ryan Houdek 012805fd72 Fixes multiblock and a few bugs in RA. 
This makes it so multiblock can now be enabled with the JITs.
Results in a decent performance increase by itself.

Ryan Houdek 7a43b3150b Fixes bug in frontend displacement calculation 
When an instruction had a literal and also a SIB displacement then this
was causing it to be calculated incorrectly.

Ryan Houdek 6d92146578 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.
