Tess Strickland 93b84b5b52 [vm/compiler] Simplify range analysis for IntConverter.
We can simplify and improve the range analysis in IntConverter if we
generalize based on the sizes and signs of the source and target
representations and whether the operation truncates or deoptimizes.

Adds RepresentationUtils::MinValue() and ::MaxValue(), which return the
minimum and maximum value (as an int64_t) for an unboxed integer
representation.
