Yes, please reopen PR 39943 as a regression for 4.3 and 4.4.

As for comment #2:

The sequence from comment #1 should be implemented in a backend due to use of
cmpltps and andps. We should invent IX86_BUILTIN_CVTUDQ2PS that expands to the
sequence via ix86_build_const_vector.

(See for example recent IX86_BUILTIN_CPYSGNP? if you want to give a shot at the
implementation for 4.5.0.)
