i965: Apply a homebrew workaround for GPU hang in OGLC api-texcoord.
The behavior of flushes in the hardware is a maze of twisty passages,
and strangely the VS constants appear to be loaded during a pipeline
flush instead of at the time of the packet emit according to the
simulator. On moving the STATE_BASE_ADDRESS packet to where it really
needed to live (in order for data loads by other packets to be
correct), we sometimes no longer got a flush between those packets
where we apparently needed it. This replicates the flushes implied by
a STATE_BASE_ADDRESS update, fixing the GPU hangs in OGLC and the
"engine" demo.
