o3: use new_k (size-class free lists) like plain code
Constant-size typed new inside o3 now calls rt.new_k instead of always
taking new_t/new_raw. new_k and recycle_leaf skip the o3 argument-fatten
path the way free/recycle already do. trees o3 new/free on the x86-64
jit dropped from about 4.1 ms to about 2.7 ms per iter (matches plain).

(older llvm note was plain 9.2 / o3 12.0.) +- allocator: o3 now uses `new_k` (size-class free lists) like plain code; `new_k`/`recycle_leaf` skip the o3 arg-fatten path. after: trees plain 2.78, o3 new/free 2.71, o3 arena 0.15. still open: emit the freelist pop/push as native code inside a compiled region (today every `new_k` still leaves via a normal call). ### how the work is organized - start with `ONBOARD.md` (reading order and exact commands), then |
