As the optimizer uses more and more AST stuff, it's now time to create an "AST" module. Initially it defines following AST datastructures: * declarations: `Decl` + derived classes * `Conformance` * `SubstitutionMap` * `Type` and `CanonicalType` Some of those were already defined in the SIL module and are now moved to the AST module. This change also cleans up a few things: * proper definition of `NominalTypeDecl`-related APIs in `SIL.Type` * rename `ProtocolConformance` to `Conformance` * use `AST.Type`/`AST.CanonicalType` instead of `BridgedASTType` in SIL and the Optimizer
