ir3's lowering of variables to scratch memory has to treat 8-bit values as 16-bit ones when comparing such value's size against the given threshold since those values are handled through 16-bit half-registers. But those values can still use natural 8-bit size and alignment for storing inside scratch memory. nir_lower_vars_to_scratch now accepts two size-and-alignment functions, one used for calculating the variable size and the other for calculating the size and alignment needed for storing inside scratch memory. Non-ir3 uses of this pass can just duplicate the currently-used function. ir3 provides a separate variable-size function that special-cases 8-bit types.
