55f6b294 - [AArch64] AArch64TargetLowering::computeKnownBitsForTargetNode - add support for AArch64ISD::MOV/MVN constants (#154039)

[AArch64] AArch64TargetLowering::computeKnownBitsForTargetNode - add support for AArch64ISD::MOV/MVN constants (#154039) Add support for the following constant nodes in `AArch64TargetLowering::computeKnownBitsForTargetNode`: ``` case AArch64ISD::MOVIedit: case AArch64ISD::MOVImsl: case AArch64ISD::MVNIshift: case AArch64ISD::MVNImsl: ``` Also add `AArch64TargetLowering::computeKnownBitsForTargetNode` tests for all the MOVI constant nodes in `llvm/unittests/Target/AArch64/AArch64SelectionDAGTest.cpp` Fixes: #153159 --------- Co-authored-by: Simon Pilgrim <llvm-dev@redking.me.uk>
