X86: Put the result used for flags in an intermediate variable.
...
Using the destination register directly causes the ISA parser to treat it as a
source even if none of the original bits are used.

X86: Define fault objects to carry debug messages.
...
These faults can panic/warn/warn_once, etc., instead of instructions doing
that themselves directly. That way, instructions can be speculatively
executed, and only if they're actually going to commit will their fault be
invoked and the panic, etc., happen.

X86: Create a directory for files that define register indexes.
...
This is to help tidy up arch/x86. These files should not be used external to
the ISA.

A batch of changes and fixes. Macroops are now generated automatically, multiops do alot more of what they're supposed to (excluding memory operands), and microops are slightly more implemented.
