GenTypeArgsAux fed the partial application `GenTypeArgAux cenv m tyenv` to List.map, so every IL generic type-instantiation heap-allocated the mapping closure (ilTypeInst@655, 21.9 MB sampled) on one of the hottest codegen paths. ListInline.map folds the mapping in, so nothing is allocated per instantiation. Co-authored-by: Copilot App <223556219+Copilot@users.noreply.github.com>
