[PARISC] Take into account nullified insn and lock functions for profiling
export profile_pc() symbol - oprofile needs it when built as a module.

Take into account nullified insn and lock functions for profiling
This is needed at the end of functions; it is typical that the return
branch nullifies the next insn, which is in the next function. This
causes profiling data to show up against the "wrong" function.
We also count lock times against the locker. This is consistent with
other architectures.
