tree-optimization/116902 - vectorizer load hosting breaks UID order #2
This is another case of load hoisting breaking UID order in the
preheader, this time between two hoistings. The easiest way out is
to do what we do for the main stmt - copy instead of move.

* tree-vect-stmts.cc (sort_after_uid): Remove again.
(hoist_defs_of_uses): Copy defs instead of hoisting them so
we can zero their UID.
(vectorizable_load): Separate analysis and transform call,
do transform on the stmt copy.
* g++.dg/torture/pr116902.C: New testcase.
