i965: Update assertion to account for Gen < 7
Previously SHADER_OPCODE_MULH could only exist on Gen7+, so the
assertion assumed the Gen7+ accumulator rules. A future patch will
allow this instruction on at least Gen6, so update the assertion.
v2: Use get_lowered_simd_width instead of open coding it. Suggested by
Curro.
