9b2c6052 - Reland "[AArch64] AArch64TargetLowering::computeKnownBitsForTargetNode - add support for AArch64ISD::MOV/MVN constants" (#155696)

Reland "[AArch64] AArch64TargetLowering::computeKnownBitsForTargetNode - add support for AArch64ISD::MOV/MVN constants" (#155696) Reland #154039 Per suggestion by @davemgreen, add mask on the shift amount to prevent shifting more than the bitwidth. This change is confirmed to fix the tests failures on x86 sanitizer bots and aarch64 sanitizer bots failures. Fixes: https://github.com/llvm/llvm-project/issues/153159
