tree-optimization/99863 - clear vector CTOR TREE_SIDE_EFFECTS
When we gimplify a vector CTOR the original CONSTRUCTOR tree remains
but we fail to recompute flags such as TREE_SIDE_EFFECTS. This causes
later GENERIC folding of them in vector lowering to give up since
the match.pd machinery is careful about TREE_SIDE_EFFECTS.
Fixing this makes vector lowering produce much less garbage and
thus following the IL for PR99793 easier.
