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.
OK.   It's unclear why the patch failed to apply in the linaro tester. 
But it ran through our RISC-V tester OK.
