	PR rtl-optimization/14782
	* pa.c (emit_move_sequence): Use SFmode for 4-byte modes when doing
	the address checks for secondary reloads for loads from and stores
	to floating-point registers.
	* pa.h (EXTRA_CONSTRAINT, case T): Use SFmode for 4-byte modes
	in the address check.  Move work around for ELF32 targets to
	GO_IF_LEGITIMATE_ADDRESS.
	(GO_IF_LEGITIMATE_ADDRESS): Require constant offsets to be
	correctly aligned for DImode loads and stores.  Don't allow long
	SFmode displacements on ELF32.
