Change everything to use the cached virtPort rather than created their own each time.

This appears to work, but I don't want to commit it until it gets tested a lot more.
I haven't deleted the functionality in this patch that will come later, but one question
is how to enforce encourage objects that call getVirtPort() to not cache the virtual port
since if the CPU changes out from under them it will be worse than useless. Perhaps a null
function like delVirtPort() is still useful in that case.

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.

Each "strand" may need to have a private copy of this state, but I couldn't

This prevents writes to the thread context in o3 which was causing the

accessible state will probably need to be accessed differently if/when we get
O3 full system up and running.

X86: Initial stack frame fixes and constant shuffling.
...
The initial stack frame for x86 is now substantially more correct. The fixes made here can be back ported to SPARC and possible the other ISAs as well. The auxiliary vector types were moved to the LiveProcess base class because they are independent of ISA. Some of the types may only apply to Linux, though, so they may have to be moved.

X86: Fix popa and push with the stack pointer.
...
POPA used st instead of ld, and it didn't skip rsp. push rsp needs to store the -original- value of the stack pointer.

X86: Fix a bug with merge
...
Merge was returning the value to merge in, not the actual result of the merge.
