00d9036c62 X86: Make shift instructions set some of the flags they're supposed to. 
The flag mechanism for microops needs to be fleshd out a little more to allow
for custom flag calculation methods for certain microops. Shift is an example
where the rules for calculating OF and CF are unique.

ca84d953b9 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.

e99c56f971 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.
