milescovielloandClaude Opus 5.5 a661d4367f perf(shader): allocate a program's use lists from an arena ...

Every IR value keeps a vector of the instructions that read it, and
each one grows by reallocating on the heap. A program's values all
die with the program, so their use lists are now drawn from a bump
arena the program owns: growth is a pointer bump and freeing is
dropped. Values built outside a program keep the heap allocator, and
copies of a use list go back to the heap.
