pa.c (hppa_expand_prologue): Simplify code storing return pointer.

 	* pa.c (hppa_expand_prologue): Simplify code storing return
 	pointer.  For large (>=8k) frames with a post_store, adjust stack
 	pointer by 8k-64 first rather than by 64.  When testing with
 	VAL_14_BITS_P, always use the actual value rather than the value
 	negated.  Add blockage to prevent scheduling of spills before
 	stack frame has been created.
	(hppa_expand_epilogue): Simplify code loading return pointer.
 	Allow a slightly larger range for merge_sp_adjust_with_load case.
 	When testing with VAL_14_BITS_P, always use the actual value.
