5.7 cherry-pick of #535

Adjust the upper bound of the Range down when forming the quantification, as it expects an inclusive upper bound. Additionally, upgrade a couple of assertions to preconditions to ensure we don't silently fail byte code emission.

Resolves #478

Adjust the upper bound of the Range down when
forming the quantification, as it expects an
inclusive upper bound.
Seems like we ought to crash in a release build
instead of potentially crashing during byte code
emission or silently failing to match.
