Return the pointer to the first instruction of a function given a function pointer.

For Itanium CPUs, all function calls are made through a PLABEL, so a pointer to a function

is actually a pointer to a PLABEL. The pointer to the first instruction of the function
|

is contained within the PLABEL. This macro may be used to retrieve a pointer to the first

instruction of a function independent of the CPU architecture being used. This is very

useful when printing function addresses through DEBUG() macros.
