Log:
Move pa.h FUNCTION_ARG_SIZE to pa.c (PR83858)

The port-local FUNCTION_ARG_SIZE:

  ((((MODE) != BLKmode \
     ? (HOST_WIDE_INT) GET_MODE_SIZE (MODE) \
     : int_size_in_bytes (TYPE)) + UNITS_PER_WORD - 1) / UNITS_PER_WORD)

is used by code in pa.c and by ASM_DECLARE_FUNCTION_NAME in som.h.
Treating GET_MODE_SIZE as a constant is OK for the former but not
the latter, which is used in target-independent code.  This caused
a build failure on hppa2.0w-hp-hpux11.11.
