Optimize hot paths for ownership transfer and the dominant data shape

Summary#

Performance regressions often come from generic safety-preserving translations that ignore actual runtime distributions. Profile first, then redesign data movement and container choice around the common case so memory and allocation costs drop without changing external behavior.

Problem#

Compiler code deep-cloned large transformed bodies unnecessarily, and alias-tracking stored mostly single-element sets in heap-allocated hash sets, inflating memory churn and wall time.

Solution#

Move data when the source is no longer needed, and replace general-purpose heap structures with small inline representations that spill only for the rare larger case.

Failure Modes#

Optimizations assume ownership is free to transfer when later passes still need the original data.
Inline-specialized containers complicate edge cases and degrade rare large workloads.
Changes land without representative profiling, so complexity increases without measurable benefit.
