Guarantee that
newarrays generated from transformations of array clone calls will always be zero initialized, ensuring array allocation is done inline, whetherTR_disableSkipZeroInitInVPis enabled or not.While investigation and development into a fix for a bug caused by corruption of a TLH pointer forcing out of line array allocation when we skip zero initialization is ongoing, this PR will provide a temporary performance boost at the (rare and minor) expense of occasional zero initialization of arrays that don't need to be zero initialized.
