marcel 01fd13440d Move the kernel-specific logic to adjust frompc from MI to MD. For 
these two reasons:
1. On ia64 a function pointer does not hold the address of the first
   instruction of a functions implementation. It holds the address
   of a function descriptor. Hence the user(), btrap(), eintr() and
   bintr() prototypes are wrong for getting the actual code address.
2. The logic forces interrupt, trap and exception entry points to
   be layed-out contiguously. This can not be achieved on ia64 and is
   generally just bad programming.

The MCOUNT_FROMPC_USER macro is used to set the frompc argument to
some kernel address which represents any frompc that falls outside
the kernel text range. The macro can expand to ~0U to bail out in
that case.
The MCOUNT_FROMPC_INTR macro is used to set the frompc argument to
some kernel address to represent a call to a trap or interrupt
handler. This to avoid that the trap or interrupt handler appear to
be called from everywhere in the call graph. The macro can expand
to ~0U to prevent adjusting frompc. Note that the argument is selfpc,
not frompc.

This commit defines the macros on all architectures equivalently to
the original code in sys/libkern/mcount.c. People can take it from
here...
