Niko Matsakis 909957793e Add a boolean flag to ExistentialBounds tracking whether the
region-bound is expected to change in Rust 1.3, but don't use it for

the type (it's not part of the formal model) so we have to normalize
this away or trans starts to get confused because two equal types wind
up with distinct LLVM types.
