pa.c (compute_frame_size): Use UNITS_PER_WORD instead of hardwired value of 4.

Browse Source 
* pa.c (compute_frame_size): Use UNITS_PER_WORD instead of hardwired
        value of 4.  Allocate 8 bytes for each FP register save.
        (hppa_expand_epilogue): Use UNITS_PER_WORD instead of harwarewired
        value of 4.
        (hppa_expand_prologue): Likewise.
        * pa.h (PROMOTE_MODE): Likewise.
        (HARD_REGNO_MODE_OK, FUNCTION_ARG_SIZE): Likewise.
        (FUNCTION_ARG_BOUNDARY): Likewise.
