JIT: update non-null assertion prop to destructure VNs (#49238)

In addition to checking for assertions based on the VN of an address, try and
destructure the VN to find the "base" address, and check its VNs as well.

This lets us get rid of some extra null checks, typically ones that are at
an offset from an existing non-null pointer.

Closes #49180.
