i965/fs: Eliminate the magic nature of virtual GRF 0.

This was a debugging aid at one point -- virtual grf 0 should never be
allocated, and it would be used if undefined register access occurred
in codegen.  However, it made the confusing register allocation code
even more confusing by indexing things off of 1 all over.
