Description
When an array is in the broadcast, it falls back to a full indexing form. A better thing to do would be recursive views via @generated functions, but to get v0.7 working this is being skipped over for now.

Research direction
Start by locating the broadcasting path where arrays fall back to full indexing. Read the surrounding broadcast implementation and investigate how recursive views via Julia's @generated functions could support the fast path. Done means array broadcasting no longer uses the full indexing form while preserving the intended v0.7 behavior.
