[RISC-V] correct machine mode in save-restore cfi RTL.
gcc/ChangeLog:
* config/riscv/riscv.cc (riscv_adjust_libcall_cfi_prologue): Use Pmode
for cfi reg/mem machmode
(riscv_adjust_libcall_cfi_epilogue): Use Pmode for cfi reg machmode
gcc/testsuite/ChangeLog:
* gcc.target/riscv/save-restore-cfi-2.c: New test to check machmode
for cfi reg/mem.
