CheckQuery calls drm_intel_bo_references to see if the batch references
the query BO, and if so, flushes. It then checks if the query BO is
busy, and if not, calls gen6_queryobj_get_results().
Stupidly, gen6_queryobj_get_results() immediately did a second redundant
drm_intel_bo_references check, even though we know the buffer is not
referenced and in fact idle.
This patch moves the batch-flush check out of gen6_queryobj_get_results
and into WaitQuery() (the other caller). That way, both callers do a
single batch-flush check.
This should only be a minor improvement, since it would only affect
the first CheckQuery call where the result is actually available.

If query->bo == NULL, this is a redundant CheckQuery call, and we
should simply return. We didn't do anything anyway - we skipped the
batch flushing block, and although we called get_results(), it has an
early return and does nothing. Why bother?

q->Ready means that the results are in, and core Mesa is free to return
them to the application. gen6_queryobj_get_results() is a natural place
to set that flag; doing so means callers don't have to.
The older non-hardware-context aware code couldn't do this, because we
had to call brw_queryobj_get_results() to gather intermediate results
when we ran out of space for snapshots in the query buffer. We only
gather complete results in the Gen6+ code, however.

This fixes 4 vertexid related piglit tests with llvmpipe due to switching
behavior of vertexid to the one gl expects.
(Won't fix non-llvm draw path since we don't get the basevertex currently.)
Plus a new PIPE_CAP_VERTEXID_NOBASE query. The idea is that drivers not
supporting vertex ids with base vertex offset applied (so, only support
d3d10-style vertex ids) will get such a d3d10-style vertex id instead -
with the caveat they'll also need to handle the basevertex system value
too (this follows what core mesa already does).
Additionally, this is also useful for other state trackers (for instance
llvmpipe / draw right now implement the d3d10 behavior on purpose, but
with different semantics it can just do both).
Doesn't do anything yet.
And fix up the docs wrt similar values.
v2: incorporate feedback from Brian and others, better names, better docs.

r600, rv610 and rv630 all have a bug in their GPR indexing
and how the hw inserts access to PV.
If the base index for the src is the same as the dst gpr
in a previous group, then it will use PV instead of using
the indexed gpr correctly.
The workaround is to insert a NOP when you detect this.
v2: add second part of fix detecting DST rel writes followed
by same src base index reads.
v3: forget adding stuff to structs, just iterate over the
previous node group again, makes it more obvious.
v3.1: drop local_nop.
Fixes ~200 piglit regressions on rv635 since SB was introduced.
