X86: Major rework of how regop microops are generated. The new implementation uses metaclass, and gives a lot more precise control with a lot less verbosity. The flags/no flags reg/imm variants are all handled by the same python class now which supplies a constructor to the right C++ class based on context.

SPARC: Make nops have the IsNop flag set. In O3, a nop is used to carry faults down the pipeline that didn't originate from an instruction. If the instruction doesn't do anything, that is just returns NoFault, but doesn't have IsNop set, the NoFault will overwrite the fault that's being sent down and nothing will happen.

SPARC: Move tlb state into the tlb. Each "strand" may need to have a private copy of this state, but I couldn't find anywhere in the spec that said that after looking briefly. This prevents writes to the thread context in o3 which was causing the pipeline to be flushed and stopping any forward progress. The other ASI accessible state will probably need to be accessed differently if/when we get O3 full system up and running.
