stage2: comment out failing test cases; implement more things

* comment out the failing stage2 test cases (so that we can uncomment the ones that are newly passing with further commits) * Sema: implement negate, negatewrap * astgen: implement field access, multiline string literals, and character literals * Module: when resolving an AST node into a byte offset, use the main_tokens array, not the firstToken function
