Struct StackSlotColoring 

pub struct StackSlotColoring<V> { /* private fields */ }

Deterministic stack-slot assignment for target-owned spill homes.

Backends retain responsibility for choosing spill values and translating a slot number into their frame layout. This helper conservatively projects each exact sparse interval to a linear block-order envelope, then reuses slots with a sweep. Envelope overlap may miss a legal reuse across a sparse gap, but cannot make interfering homes alias. The algorithm is independent of target MIR and opcode semantics and runs in O(n log n).
