Fold more vector constants early
In PR105049 we had
return VIEW_CONVERT_EXPR<U>( VEC_PERM_EXPR < {<<< Unknown tree: compound_literal_expr
V D.1984 = { 0 }; >>>, { 0 }} , {<<< Unknown tree: compound_literal_expr
V D.1985 = { 0 }; >>>, { 0 }} , { 0, 0 } > & {(short int) SAVE_EXPR <c>, (short int) SAVE_EXPR <c>});
where we gimplify the init CTORs to
_1 = {{ 0 }, { 0 }};
_2 = {{ 0 }, { 0 }};
instead of to vector constants. The following makes sure to simplify the
CTORs to VECTOR_CSTs during gimplification by re-ordering the simplification
to after CTOR flag recomputation and gimplification of the elements.

* gimplify.cc (gimplify_init_constructor): First gimplify,
then simplify the result to a VECTOR_CST.
