Fix #4654 (#5749)gh-9567

Apparently AST for ldc is an abuse of terminology, as it doesn't
produces anything resembling a syntax tree:
https://github.com/dlang/dmd/pull/6556#issuecomment-282353400 . It is
potentially meaningful only to ldc developers. Anyway the `generateAST`
result type is fixed, along with some other small stuff around.
