re PR target/26255 (internal compiler error: in reload_cse_simplify_operands, at postreload.c:391)

	PR target/26255
	* pa.md: Create separate HI and QI move patterns for 32-bit and 64-bit
	with hardware float support, and software float support.  Add fcpy
	alternative to hardware patterns.  Add alternatives to copy between
	general and floating-point registers to the 32-bit pattern.
	* pa.c (pa_secondary_reload): Don't abort if reload tries to find a
	secondary reload to load a QI or HI mode constant into a floating
	point register.
	* pa32-regs.h (VALID_FP_MODE_P): Allow QImode and HImode.
	* pa64-regs.h (VALID_FP_MODE_P): Likewise.
