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
