Log:
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.
