[PATCH] D32938: [ARM][NEON] Add support for ISD::ABS lowering

[Simon Pilgrim via Phabricator via llvm-commits]

RKSimon created this revision.
Herald added subscribers: javed.absar, aemerson.

Update NEON int_arm_neon_vabs intrinsic to use the ISD::ABS opcode directly

Added constant folding tests - I'm not sure what is the accepted ARM approach for testing constants.
