Fix in-scope set in simplifier
This patch fixes Trac #14408. The problem was that the StaticEnv
field of an ApplyToVar or Select continuation didn't have enough
variables in scope. The fix is simple, and I documented the
invariant in Note [StaticEnv invariant] in SimplUtils.
No change in behaviour: this just stops an ASSERT from tripping.
