Nelson Chu 00d4d1b0a3 RISC-V: Support to add implicit extensions for G. 
G is a special case, consider the ISA spec github issue as follows,
https://github.com/riscv/riscv-isa-manual/issues/575

My understand is that - i, m, a, f and d extensions are not g's implicit
extensions, they are g's expansions.  The zifencei is the implicit extension
of g, and so is zicsr, since it is implicited by f (or i2p1).  However,
we add the g with the RISCV_UNKNOWN_VERSION to the subset list, and it
will not output to the arch string, it is only used to check what implicit
extensions are need to be added.

	bfd/
	* elfxx-riscv.c (riscv_parse_add_subset): Allow to add g with
	RISCV_UNKNOWN_VERSION versions.
	(riscv_parse_std_ext): Add g to the subset list, we only use it
	to add the implicit extensions, but won't output it to arch string.
	(riscv_parse_add_implicit_subsets): Add implicit zicsr and zifencei
	for g extension.
	(riscv_arch_str1): Do not output g to the arch string.
	* elfxx-riscv.h (RISCV_UNKNOWN_VERSION): Moved to include/opcode/riscv.h.

	gas/
	* testsuite/gas/riscv/attribute-10.d: Updated.
	* testsuite/gas/riscv/march-imply-g.d: New testcase for g.
	* testsuite/gas/riscv/march-imply-unsupported.d: The zicsr and zifencei
	are not supported in the ISA spec v2.2, so don't add and output them.

	include/
	* opcode/riscv.h (RISCV_UNKNOWN_VERSION): added.
