Log message:
	* function.c (STACK_ALIGNMENT_NEEDED): New macro.  Default to 1.
	(assign_stack_local_1): Perform overall stack alignment only when
	STACK_ALIGNMENT_NEEDED is non-zero.
	* doc/tm.texi (STACK_ALIGNMENT_NEEDED): Document.
	
	* pa.c (compute_frame_size): Rename fsize to size.  Account for
	alignment to a word boundary before general register save block.  Only
	account for double-word alignment before floating point register save
	block if one or more are saved.  Don't allocate space for %r3 when
	frame pointer is needed.
	(hppa_expand_prologue): Include alignment to word boundary in local
	frame size.
	* pa.h (STARTING_FRAME_OFFSET): Define to 8 on both 32 and 64-bit ports.
	(STACK_ALIGNMENT_NEEDED): Define.
