Previously the `ConcreteDeclaration` and `InlineDeclaration` had different properties for the underlying node type. And the `InlineDeclaration` did not store a value that represented its declaration. It turns out that a natural declaration node for an inline type is the expression. For example in UMD/CommonJS this would be the `exports.<name>` property access node. So this expression is now used for the `node` of `InlineDeclaration` types and the `expression` property is dropped. To support this the codebase has been refactored to use a new `DeclarationNode` type which is a union of `ts.Declaration|ts.Expression` instead of `ts.Declaration` throughout. PR Close #38959
Angular Compatibility Compiler (ngcc)
This compiler will convert node_modules compiled with ngc, into node_modules which
appear to have been compiled with ngtsc.
This conversion will allow such "legacy" packages to be used by the Ivy rendering engine.
