x86 fixes
...
Make the emulation environment consider the rex prefix.
Implement and hook in forms of j, jmp, cmp, syscall, movzx
Added a format for an instruction to carry a call to the SE mode syscalls system
Made memory instructions which refer to the rip do so directly
Made the operand size overridable in the microassembly
Made the "ext" field of register operations 16 bits to hold a sparse encoding of flags to set or conditions to predicate on
Added an explicit "rax" operand for the syscall format
Implemented syscall returns.

Refactored the x86 isa description some more. There should be more seperation between x86 specific parts, and those parts which are implemented in the isa description but could eventually be moved elsewhere.

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.

Break out the one and two byte opcodes into different files. Also change what bits decode is done on to reflect where clumps of instructions are.

Stub decoder. This is probably even farther from finished than it looks...
