Ben Clayton 451eee0fed tint: Stub intrinsic @const evaluation
Add support for @const to builtins in intrinsics.def.
Propagate this flag through to the intrinsic table.
Handle builtins that are @const annotated in the resolver.

Currently no intrinsics are decorated with @const, so there's nothing to
test (yet).
