For 32/64bit we can avoid explicit extension/zeroing as the instructions
set the full width of the registers.

When doing 16/8bit computation we have to put a bit more work in so we
can't use the fast path.

Fixes #23749 for 9.4.

(cherry picked from commit 0bb44f695bd008f03644e3d306566c50c5bd528c)
