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.
@param FunctionPointer A pointer to a function.
@return The pointer to the first instruction of a function given a function pointer.
