Log Message:
Fix kernel profiling on HPPA.

- stop gcc emitting stuff that HPUX requires
- don't use splhigh() in MCOUNT_ENTER as a call to _mcount will be
  generated at the moment. Disable interrupts in hardware instead.
- Fix _PROF_PROLOGUE to save/restore all the register args when calling
  _mcount.
- Fixup LEAF_ENTRY to dtrt (I think) in the GPROF case.
- Provide LEAF_ENTRY_NOPROFILE and sprinkle its use where i) profiling
  causes problems, e.g. trap handlers, and ii) where it just doesn't
  make sense, e.g. start.
