Created attachment 652117 [details] [diff] [review]

This came in with the latest m-c merge. The problem is that if a lookup is uncacheable (in this case a missing property on a dense array), but we don't disable the IC, we were still inlining the shape in Ion.

This patch changes things so that we only inline a monomorphic getprop/setprop in Ion if all lookups were cacheable.
