There were a couple of problems with the way the trace buffer state is saved/restored in assembly. The DEBUG_HWTRACE_SAVE/RESTORE macros save a value to the stack, which is not immediately obvious; the CPLB exception code needed changes to load the correct value of the stack pointer. The other problem is that the SAVE/RESTORE macros weren't pushing and popping the value downwards on the stack, but rather moving it _upwards_, which is of course completely broken. We also need to make sure there's a matching DEBUG_HWTRACE_RESTORE in the error case of the CPLB handler.
