arm: Disambiguate multiple crypto patterns with the same name.

arm: Disambiguate multiple crypto patterns with the same name.

No functional change, but arm/crypto.md has multiple pattenrs all
called crypto_<crypto_pattern>, which makes references to them
ambiguous, so add the iterator base to the pattern name so that it is
distinct in the commit logs.

gcc/ChangeLog:

	* config/arm/crypto.md (crypto_<CRYPTO_AESMC:crypto_pattern>): Add
	iterator to pattern name to disambiguate.
	(crypto_<CRYPTO_AES:crypto_pattern>): Likewise.
	(crypto_<CRYPTO_BINARY:crypto_pattern>): Likewise.
	(crypto_<CRYPTO_TERNARY:crypto_pattern>): Likewise.
	(crypto_<CRYPTO_SELECTING:crypto_pattern>): Likewise.
	(crypto_<CRYPTO_SELECTING:crypto_pattern>_lb): Likewise.
