Iain Ireland 0a8be1129a Bug 1951338: Add fast path for packed elements in willBeSparseElements r=jandem
I originally intended to reset the NON_PACKED flag in this code if there were no holes, but after a closer look, I realized that we exit early from the loop once we've seen enough non-holes, but resetting the flag would require us to examine every element.
