Jim Wilson 1080bf78c0 RISC-V: Accept version, supervisor ext and more than one NSE for -march.
This patch moves all -march parsing logic into bfd, because we will use this
code in ELF attributes.

	(struct riscv_subset_t): New structure.
	(riscv_subset_t): New typedef.

	(riscv_release_subset_list): New prototype.
	(riscv_add_subset): Likewise.
	(riscv_lookup_subset): Likewise.
	(riscv_lookup_subset_version): Likewise.
	(riscv_release_subset_list): Likewise.
	* elfxx-riscv.c: Include safe-ctype.h.
	(riscv_parsing_subset_version): New function.

	gas/
	* config/tc-riscv.c: Include elfxx-riscv.h.
	(struct riscv_subset): Removed.
	(riscv_subsets): Change type to riscv_subset_list_t.
	(riscv_subset_supports): Removed argument: xlen_required and move
	logic into libbfd.
	(riscv_multi_subset_supports): Removed argument: xlen_required.
	(riscv_clear_subsets): Removed.
	(riscv_add_subset): Ditto.
	(riscv_set_arch): Extract parsing logic into libbfd.
	(riscv_ip): Update argument for riscv_multi_subset_supports and
	riscv_subset_supports. Update riscv_subsets due to struct definition
	changed.
	(riscv_after_parse_args): Update riscv_subsets due to struct
	definition changed, update and argument for riscv_subset_supports.
