hppa: Add peephole2 optimizations for REG+D loads and stores
The PA 1.x architecture only supports long displacements in
integer loads and stores. Floating-point loads and stores
only support short displacements. As a result, we have to
wait until reload is complete before generating insns with
long displacements.
The PA 2.0 architecture supports long displacements in both
integer and floating-point loads and stores.
The peephole2 optimizations added in this change are only
enabled when 14-bit long displacements aren't supported for
floating-point loads and stores.

gcc/ChangeLog:
* config/pa/pa.h (GENERAL_REGNO_P): Define.
* config/pa/pa.md: Add SImode and SFmode peephole2
patterns to generate loads and stores with long
displacements.
