StackColoring: smarter check for slot overlap
Summary:
The old check for slot overlap treated 2 slots `S` and `T` as
overlapping if there existed a CFG node in which both of the slots could
possibly be active. That is overly conservative and caused stack blowups
in Rust programs. Instead, check whether there is a single CFG node in
which both of the slots are possibly active *together*.
Fixes PR32488.
