riscv: Restructure callee-saved register save/restore code
This patch restructures the loop over the GP registers
which saves/restores then as part of the prologue/epilogue.
No functional change is intended by this patch, but it
offers the possibility to use load-pair/store-pair instructions.
gcc/ChangeLog:
* config/riscv/riscv.cc (riscv_next_saved_reg): New function.
(riscv_is_eh_return_data_register): New function.
(riscv_for_each_saved_reg): Restructure loop.
