    tree-optimization/105173 - fix insertion logic in reassoc

    The find_insert_point logic around deciding whether to insert
    before or after the found insertion point does not handle
    the case of _12 =3D ..;, _12, 1.0 well.  The following puts the
    logic into find_insert_point itself instead.

            * tree-ssa-reassoc.cc (find_insert_point): Get extra
            insert_before output argument and compute it.
            (insert_stmt_before_use): Adjust.
            (rewrite_expr_tree): Likewise.
