i965: STATIC_ASSERT that there aren't too many BRW_NEW_* flags.
We are getting close to the maximum number of BRW_NEW_* bits that can
be stored in brw->state.dirty.brw without overflowing 32 bits, and
geometry shaders are going to add more. Add a STATIC_ASSERT so that
we will be alerted when we need to switch to 64 bits.
