[InstSimplify] Support ptrtoaddr in simplifyICmpInst() (#171985) ...

This is basically the same change as #162653, but for InstSimplify
instead of ConstantFolding.

It folds `icmp (ptrtoaddr x, ptrtoaddr y)` to `icmp (x, y)` and `icmp
(ptrtoaddr x, C)` to `icmp (x, inttoptr C)`.

The fold is restricted to the case where the result type is the address
type, as icmp only compares the icmp bits. As in the other PR, I think
in practice all the folds are also going to work if the ptrtoint result
type is larger than the address size, but it's unclear how to justify
this in general.
