Gabe Black e524240d68 Make disassembled x86 register indices reflect their size. 
This doesn't handle high byte register accesses. It also highlights the fact that address size isn't actually being calculated, and that the size a microop uses needs to be overridable from the microassembly.

Gabe Black c4004482a5 Make "test" set some condition codes. 
It still needs to zero the overflow and carry flags to be correct.

Gabe Black a6757095c3 Add in support for condition code flags. 
Some microops can set the condition codes, and some of them can be predicated on them. Some of the codes aren't implemented because it was unclear from the AMD patent what they actually did. They are used with string instructions, but they use variables IP, DTF, and SSTF which don't appear to be documented.

This is stored in the integer register file so that it can be renamed, but it should be a misc reg.
