Add an option to the lexer to go back and get a list of "full" tokens, which include their leading and trailing trivia, which we can index into from SourceLocs in the current AST. This starts the Syntax sublibrary, which will support structured editing APIs. Some skeleton support and basic implementations are in place for types and generics in the grammar. Yes, it's slightly redundant with what we have right now. lib/AST conflates syntax and semantics in the same place(s); this is a first step in changing that to separate the two concepts for clarity and also to get closer to incremental parsing and type-checking. The goal is to eventually extract all of the syntactic information from lib/AST and change that to be more of a semantic/symbolic model. Stub out a Semantics manager. This ought to eventually be used as a hub for encapsulating lazily computed semantic information for syntax nodes. For the time being, it can serve as a temporary place for mapping from Syntax nodes to semantically full lib/AST nodes. This is still in a molten state - don't get too close, wear appropriate proximity suits, etc.
