Log message:
	PR target/21723
	* pa.md: Remove fcpy alternative from movhi and movqi patterns.
	* pa32-regs.h (HARD_REGNO_NREGS): Return two floating point registers
	for complex modes when generating code for PA 1.0.
	(VALID_FP_MODE_P): New macro.
	(HARD_REGNO_MODE_OK): Use VALID_FP_MODE_P.  Use non-overlapping register
	sets for all general and floating point modes.  Align wide floating
	point modes to even register boundaries to comply with architectural
	requirements.
	(CLASS_MAX_NREGS): Update to align with change to HARD_REGNO_NREGS.
	* pa64-regs.h (HARD_REGNO_NREGS): Update comment and formatting.
	(VALID_FP_MODE_P): New macro.
	(HARD_REGNO_MODE_OK): Use VALID_FP_MODE_P.  Use non-overlapping register
	sets for all general and floating point modes.  Align wide floating
	point modes to even register boundaries to comply with architectural
	requirements.
