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.
