  Patch v2: Change the implied ISA info using the minimum set and add
dependencies info  into the python script.

Due to the crypto vector entension is depend on the Vector extension,
so the "v" info is added into implied ISA info with the corresponding
crypto vector extension.

gcc/ChangeLog:

	* common/config/riscv/riscv-common.cc: Modify implied ISA info.
	* config/riscv/arch-canonicalize: Add crypto vector implied info.
