PA uses function descriptors like Itanium.  A function pointer is 
actually a pointer to a descriptor, and the alignment of the descriptor 
has nothing at all to do with FUNCTION_BOUNDARY.

Also, consider the arm/thumb and mips/mips16 cases, where we distinguish 
between the different types of functions by using the otherwise unused 
low order bits of the address.
