Than McIntosh ff0cf25236 Rework/enhance stack coloring data flow analysis.
Replace bidirectional flow analysis to compute liveness with forward
analysis pass. Treat lifetimes as starting when there is a first
reference to the stack slot, as opposed to starting at the point of the
lifetime.start intrinsic, so as to increase the number of stack
variables we can overlap.
