Range check relative array accesses

I'm attaching an alternative fix from bug 38711. This one SHOULD work without
regressions but it will probably have somewhat of a performance impact. AFAICS
not even ARB_robust_buffer_access_behavior guarantees any specific result. From
the spec: "Out-of-bounds reads return undefined values".

I'm not sure we want this patch in Wine but I don't know of any other "safe"
fix.
