[RISC-V] add implied extension repeatly until stable
Call handle_implied_ext repeatly until there's no
new subset added into the subset list.
gcc/ChangeLog:
* common/config/riscv/riscv-common.cc (riscv_subset_list::riscv_subset_list):
init m_subset_num to 0.
(riscv_subset_list::add): increase m_subset_num once a subset added.
(riscv_subset_list::finalize): call handle_implied_ext repeatly
until no change in m_subset_num.
* config/riscv/riscv-subset.h: add m_subset_num member.
