This was ridiculous. We were ignoring the inst->header.saturate flag in the
case of math and only math. On gen4, we would leave inst->header.saturate in
place if it happened to be set, which would end up being applied to the
implicit mov and thus trash the first argument. On gen6, we would overwrite
inst->header.saturate with the saturate flag from the argument, which was not
set appropriately in brw_vec4_emit.cpp, and was only not a bug due to our
incompetence at coalescing saturate moves.
By ripping the argument out and making saturate work just like all the other
brw_eu_emit.c code generation, we can avoid both these classes of bugs.
Fixes piglit fog-modes, and the new specific fs-saturate-exp2 case.

(cherry picked from commit f6b7157550)
On Gen4+, brw_finish_batch() calls brw_emit_query_end(), which emits
some extra PIPE_CONTROLs to capture the current occlusion query data.
Unfortunately, it was being called *after* _intel_batchbuffer_flush
added the MI_BATCH_BUFFER_END, meaning those PIPE_CONTROLs didn't get
inside the batch.
Not only does this likely cause bogus occlusion query values, it can
also cause crashes: with the recent change to use 64-bit depth count
writes on Gen6+, we started emitting an odd-length PIPE_CONTROL, which
happened after the MI_NOOP padding. This resulted in an odd-length
batch buffer, which resulted in execbuf2 returning -EINVAL and the
application dying with an intel_do_flush_locked failure.
On older generations, finish_batch() doesn't emit any state, so this
change shouldn't have any effect.

This was introduced by commit 24db6d6 (cherry-picked from a683012). The
original patch fixed potential GPU hangs on SNB, and it caused some
rendering regressions there. The benefits outweigh the costs.
However, the work-around is not necessary for pre-SNB chipsets.
Applying the work-around there gives rendering regressions with no
benefit. This patch disables the work-around on pre-SNB chipsets.
Without the original patch, the piglit test
depthstencil-render-miplevels would reliably hang an SNB GPU. On ILK
this test would not hang, and it does not hang with this patch.
