PY-48760 Implement CFG for PEP-634 match statements

Browse Source 
I introduced a new type of CFG instructions, similar to ConditionalInstruction,
called RefutablePatternInstruction. The idea is that every pattern that can
possibly fail to match is surrounded with a pair of such instructions, helping
to describe how the control flow moves in each case. The PEP calls the opposite
type of patterns that always match "irrefutable", hence the name. We need these
synthetic instructions because otherwise some refutable patterns such as literal
ones (e.g. "42") don't leave any nodes in the graph. Incorporating the information
about irrefutable patterns right into the graph allows catching cases such
as "wildcard/name capture makes remaining patterns unreachable", both in OR
patterns and independent case clauses.
