The backend emits 16 bit memory loads for single element character
vector. As a result the character will not be right justified in the

build_new_1 already passes tf_no_cleanup to build_value_init, but in this

As PR91790 exposed, when we have one slp node whose first_stmt_info_for_drptr
is different from first_stmt_info, it's possible that the first_stmt DR isn't
initialized yet before stmt SLP_TREE_SCALAR_STMTS[0] of slp node. So we
shouldn't use first_stmt_info for vect_setup_realignment, instead we can use
the one based on first_stmt_info_for_drptr DR with additional adjustment by
bumping the distance from first_stmt DR.

When concatenating a path ending in a root-directory onto another path,
