Gabe Black e2e0ae576a X86: Make sure immediate values are truncated properly.
Register values will be "picked" which will assure they don't have junk beyond
the part we're using. Immediate values don't go through a similar process, so
we should truncate them explicitly.

Gabe Black b066e717f4 ARM: Fix an instruction in the cmpxchg kernel provided routine.
The instruction was encoded as a load instead of the intended store.

Gabe Black 1e04b6281d ARM: Make the ARM native tracer stop M5 if control diverges.
If the control flow of M5's executable and statetrace's target process get out
of sync even a little, there will be a LOT of output, very little of which
will be useful. There's also almost no hope for recovery. In those cases, we
might as well give up and not generate a huge, mostly worthless trace file.

Gabe Black a41e132007 ARM: Make native trace only print when registers are changing value.
When registers have incorrect values but aren't actively changing, it's likely
they're not being modified at all. The fact that they're still wrong isn't
very important.
