This patch adds vec_load_lanes and vec_store_lanes patterns for NEON.
They feed directly into the corresponding intrinsic patterns.

Tested on x86_64-linux-gnu and arm-linux-gnueabi.  OK to install?

Richard


gcc/
	* config/arm/neon.md (vec_load_lanes<mode><mode>): New expanders,
	(vec_store_lanes<mode><mode>): Likewise.
