RISC-V: Fix -march option parsing when extension exists.
This patch fixes -march option parsing when `p` extension exists,
e.g., -march=rv64imafdcp should produce
.attribute arch, "rv64i2p0_m2p0_a2p0_f2p0_d2p0_c2p0_p"
rather than
.attribute arch, "rv64i2p0_m2p0_a2p0_f2p0_d2p0_c_p"
gcc/ChangeLog:
* common/config/riscv/riscv-common.c
(riscv_subset_list::parsing_subset_version): Fix -march option parsing
when `p` extension exists.
gcc/testsuite/ChangeLog:
* gcc.target/riscv/attribute-18.c: New test.
