Implement valtree

2021-03-12T12:16:14+00:00

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.
