static int phi_arg_index_from_use ( )

inlinestatic

Return the phi argument which contains the specified use.

Since the use is the first thing in a PHI argument element, we can calculate its index based on casting it to an argument, and performing pointer arithmetic.

 Make sure the calculation doesn't have any leftover bytes.  If it does,
 then imm_use is likely not the first element in phi_arg_d.
