        Backport from mainline
        * trans-array.h (gfc_trans_allocate_temp_array):  Add bool
        argument.
        * trans-array.c (gfc_trans_allocate_temp_array): Add extra
        argument "function" to show if we are translating a function.
        If we are translating a function, perform checks whether
        the size along any argument is negative.  In that case,
        allocate size 0.
        (gfc_trans_array_constructor):  Add funciton argument (as
        false) to gfc_trans_allocate_temp_array.
        (gfc_conv_loop_setup):  Likewise.
        * trans-expr.c (gfc_trans_function_call): Add funciton
        argument (as true) to gfc_trans_allocate_temp_array.
        * trans-stmt.c (gfc_conv_elemental_dependencies): Add funciton
        argument (as false) to gfc_trans_allocate_temp_array.
        * trans-intrinsic.c (gfc_conv_intrinsic_array_transfer):
        Likewise.
