	* pa.md: Consolidate HImode and QImode move patterns into one pattern
	each, eliminating floating-point alternatives.
	* pa-protos.h (pa_cannot_change_mode_class, pa_modes_tieable_p):
	Declare functions.
	* pa-64.h (SECONDARY_MEMORY_NEEDED): Define here.
	* pa.c (pa_secondary_reload): Use an intermediate general register
	for copies to/from floating-point register classes.  Simplify code
	SHIFT_REGS class.  Provide additional comments.
	(pa_cannot_change_mode_class, pa_modes_tieable_p): New functions.
	* pa.h (MODES_TIEABLE_P): Use pa_modes_tieable_p.
	(SECONDARY_MEMORY_NEEDED): Delete define.
	(INT14_OK_STRICT): Define.
	(MODE_OK_FOR_SCALED_INDEXING_P): Allow SFmode and DFmode when using
	soft float.
	(MODE_OK_FOR_UNSCALED_INDEXING_P): Likewise.
	(GO_IF_LEGITIMATE_ADDRESS): Use INT14_OK_STRICT in REG+D case for
	SFmode and DFmode.
	(LEGITIMIZE_RELOAD_ADDRESS): Use INT14_OK_STRICT in mask selection.
	Align DImode offsets when generating 64-bit code.
	* pa32-regs.h (VALID_FP_MODE_P): Remove QImode and HImode.
	(CANNOT_CHANGE_MODE_CLASS): Define.
	* pa64-regs.h (VALID_FP_MODE_P): Remove QImode and HImode.
	(CANNOT_CHANGE_MODE_CLASS): Define using pa_cannot_change_mode_class.
