1;; Tests that the compiler ignores smaller contexts that differ only in the2;; IsInlineFrame bool. These map to the same full context id internally, as we3;; ignore the inline frame status which may differ in feedback compiles.4;; Presumably this happens when profiles collected from different binaries are5;; merged.
