This is in contrast to emitting it directly in vkCmdPipelineBarrier. This
has a couple of advantages. First, it means that no matter how many
vkCmdPipelineBarrier calls the application strings together it gets one or
two PIPE_CONTROLs. Second, it allow us to better track when we need to do
stalls because we can flag when a flush has happened and we need a stall.

Instead of blasting it out as part of the pipeline, we put it in the
command buffer and only blast it out when it's really needed. Since the
PUSH_CONSTANT_ALLOC commands aren't pipelined, they immediately cause a
stall which we would like to avoid.

This fixes a "regression" on Haswell and prior caused by merging the gen7
and gen8 flush_state functions. Haswell should still work just fine if
you're on a 4.4 kernel, but we really should make it detect the command
parser version and do something intelligent.
This fixes many CTS cases, but will require an update to the kernel
command parser register whitelist. (The CS GPRs and TIMESTAMP
registers need to be whitelisted.)
