intel/fs/vec4: add missing dependency in write-on-write fixed GRFs


If we load constant data using pull constant SENDS, and we later load
that register with some other data, we can end up in a situation where
we don't track the initial fixed register write and therefore end up
using uninitialized registers.

This tracks write-on-write of fixed GRFs like we do for normal virtual
GRFs.

v2: Fix post_alloc_reg case (Jason)
