Only AArch64ISD::MOVI is currently handled, preventing later value tracking based folds from recognizing lowered constants
I don't know much about these nodes, but all of these might be eventual candidates forAArch64TargetLowering::computeKnownBitsForTargetNode:
```
case AArch64ISD::MOVI:
case AArch64ISD::MOVIshift:
case AArch64ISD::MOVIedit:
case AArch64ISD::MOVImsl:
case AArch64ISD::MVNIshift:
case AArch64ISD::MVNImsl:
```
Noticed while trying to triage #148191
