> Yeah, this makes no sense whatsoever.  The base is the array.  Your fix makes it so that every array access becomes a generic access (i.e. function call).  It defeats the whole purpose of having an optimizing compiler.

If it's own type is Array::Unprofiled and index is Int32SpeculatedType, It will crash.
So I changed order of returning ArrayMode(Array::ForceExit) when type() is Array::Unprofiled.
Regardless index is Int32Speculation or not, Array::Unprofiled type has the highest priority.
