zGoldthorpe 25dcd231bf [IPO] Added attributor for identifying invariant loads (#141800) ...

The attributor conservatively marks pointers whose loads are eligible to
be marked as `!invariant.load`.
It does so by identifying:
1. Pointers marked `noalias` and `readonly`
2. Pointers whose underlying objects are all eligible for invariant
loads.

The attributor then manifests this attribute at non-atomic non-volatile
load instructions.
