So, what N do you want to use for SSA_NAME_RANGE_INFO?
N=255 wouldn't be very space efficient especially if the common case is a
single range or two.
For such cases making e.g. m_len not an embedded array, but pointer to
somewhere after the HOST_WIDE_INT array in the same allocation would be
better.
