Research direction

Start with PR 5708, which demonstrates the inconsistent multiplier for the same extent Val*. Then inspect the PrecomputedValues and FusionExecutorCache context described in PR 5082; the work is done when one Val* cannot be bound to different values for the same FusionExecutorCache instance and PR 5082 is no longer blocked.

Description

As demonstrated in https://github.com/NVIDIA/Fuser/pull/5708, The same extent Val* could have different multiplier. This is a blocker for my PR https://github.com/NVIDIA/Fuser/pull/5082, because this could lead to PrecomputedValues binding the same Val* with different value for the same instance of FusionExecutorCache.
