Fortunately we don't have any extension really defined is prefixed
with `h`, so we can just change that.
gcc/ChangeLog:
* common/config/riscv/riscv-common.cc (riscv_ext_version_table):
Add `h`.
(riscv_supported_std_ext): Ditto.
(multi_letter_subset_rank): Remove `h`.
(riscv_subset_list::parse_std_ext): Handle `h` as single letter
extension.
(riscv_subset_list::parse): Ditto.
gcc/testsuite/ChangeLog:
* testsuite/gcc.target/riscv/arch-18.c: New.
* testsuite/gcc.target/riscv/arch-5.c: Remove test for prefixed
with `h`.
* testsuite/gcc.target/riscv/predef-23.c: New.
OK.
