Fix Arm big-endian regressions.

gcc/ChangeLog:

	* config/arm/arm-protos.h (neon_vcmla_lane_prepare_operands): Remove patternmode.
	* config/arm/arm.c (neon_vcmla_lane_prepare_operands): Likewise.
	* config/arm/neon.md (neon_vcmla_lane<rot><mode>, neon_vcmla_laneq<rot><mode>,
	neon_vcmlaq_lane<rot><mode>): Remove endianness conversion.
