org.antlr.v4.runtime.atn.CodePointTransitions

Utility class to create AtomTransition, RangeTransition, and SetTransition appropriately based on the range of the input. Previously, we distinguished between atom and range transitions for Unicode code points <= U+FFFF and those above. We used a set transition for a Unicode code point > U+FFFF. Now that we can serialize 32-bit int/chars in the ATN serialization, this is no longer necessary.
