[ic] Don't allow hole to undefined conversions for double arrays

This CL fixes a perf regression caused by:
https://chromium-review.googlesource.com/c/v8/v8/+/1465182

A deopt loop was occurring for HOLEY_DOUBLE_ELEMENTS arrays when hole
elements were used as anything other than a float64, such as a return
value or storing into a non-double array.
