[PATCH] RISC-V: Make stack_save_restore_2 more robust

[Patrick O'Neill]

GCC recently changed to emit __riscv_restore_5 which causes this
testcase to fail.
This patch updates the regex to be more robust to change by accepting
any number after __riscv_save_ and __riscv_restore_.

gcc/testsuite/ChangeLog:

        * gcc.target/riscv/stack_save_restore_2.c: Accept any number
        after __riscv_save_ and __riscv_restore_.

Tested using glibc rv64gc on r14-4980-g2672c60917d.
