nir/intrinsics: Allow deref sources to consume anything

Browse Source 
This commit adds a new num_components value for intrinsic sources of -1
which means that it consumes everything and the number of components
effectively isn't validated.  This is useful for deref sources which
just take the result of the deref and we leave it up to the driver to
decide what that size should be.
