Ben Clayton a9156ff091 Rework Resolver so that we construct semantic types in a single pass. ... The semantic nodes cannot be fully immutable, as they contain cyclic references. Remove Resolver::CreateSemanticNodes(), and instead construct and mutate the semantic nodes in the single traversal pass. Give up on trying to maintain the 'authored' type names (aliased names). These are a nightmare to maintain, and provided limited use. Significantly simplfies the Resolver, and allows us to generate more semantic to semantic references, reducing sem -> ast -> sem hops. Note: This change introduces constant value propagation across constant variables. This is unlocked by the earlier construction of the sem::Variable.
