CTFE/Miri engine Pointer type overhaul: make Scalar-to-Pointer conversion infallible
...
This resolves all the problems we had around "normalizing" the representation of a Scalar in case it carries a Pointer value: we can just use Pointer if we want to have a value taht we are sure is already normalized.

CTFE core engine allocation & memory API improvemenets
...

Implement valtree
...
valtree is a version of constants that is inherently safe to be used within types.
This is in contrast to ty::Const which can have different representations of the same value. These representation differences can show up in hashing or equality comparisons, breaking type equality of otherwise equal types.
valtrees do not have this problem.
