radeonsi: fix blitting the last 2 mipmap levels of compressed textures

This fixes compressedteximage piglit tests.

+10 piglits

Evergreen and Cayman have the same issue. R600 and R700 don't.

cherry-ignore: Update for newly-backported commit

This commit was recently backported by Marek, so we can drop the exception from cherry-ignore now.
Remove error when calling glGenQueries/glDeleteQueries while a query is active

There is nothing in the OpenGL specification which prevents the user from
calling glGenQueries to generate a new query object while another object is
active. Neither is there anything in the Mesa implementation which prevents
this. So remove the INVALID_OPERATION errors in this case.

Similarly, it is explicitly allowed by the OpenGL specification to delete an
active query, so remove the assertion for that case, replacing it with the
necesssary state updates to end the query, (clear the bindpt pointer and call
into the driver's EndQuery hook).

st/mesa: move out of memory check in st_draw_vbo()

Before we were only checking the st->vertex_array_out_of_memory flag
after updating array state.  But if there's two consecutive glDrawArrays
calls and the first one is skipped because of OOM, the second one should
be skipped too.

i965: CS writes/reads should use I915_GEM_INSTRUCTION

Otherwise the gen6 w/a in the kernel won't kick in and the write will
land nowhere.

Inspired by a patch Ken pointed me at which had the same issue (but
isn't yet merged and also for a gen7+ feature). An audit of the entire
driver didn't reveal any other case than the one in in the write_reg
helper used by the gen6 queryobj code.

i965: Emit post-sync non-zero flush before 3DSTATE_GS_SVB_INDEX.

From the comments above intel_emit_post_sync_nonzero_flush:
"[DevSNB-C+{W/A}] Before any depth stall flush (including those
 produced by non-pipelined state commands), software needs to first
 send a PIPE_CONTROL with no bits set except Post-Sync Operation != 0."

This suggests that every non-pipelined (0x79xx) command needs a
post-sync non-zero flush before it.

i965: Move post-sync non-zero flush for 3DSTATE_MULTISAMPLE.

For some reason, we put the flush in the caller, rather than just before
emitting the packet.  This is more than a cosmetic problem: BLORP calls
gen6_emit_3dstate_multisample() directly, and so it missed the flush.

i965: Also emit HIER_DEPTH and STENCIL packets when disabling depth.

From the documentation:
"[DevIVB] 3DSTATE_DEPTH_BUFFER must always be programmed along with the
 other Depth/Stencil state commands(i.e. 3DSTATE_CLEAR_PARAMS,
 3DSTATE_STENCIL_BUFFER, or 3DSTATE_HIER_DEPTH_BUFFER)."

We normally do this, but BLORP was failing to do so in the case where it
disables depth.

Not observed to fix anything yet.

The normal drawing path does this, and it's necessary on Ivybridge,
so let's try it on Sandybridge too.  It's not explicitly documented
as necessary, but might help with hangs.

meta: enable vertex attributes in the context of the newly created array object

Otherwise, the function would enable generic vertex attributes 0
and 1 of the array object it does not own. This was causing crashes
in Euro Truck Simulator 2, since the incorrectly enabled generic
attribute 0 in the foreign context got precedence before vertex
position attribute at later time, leading to NULL pointer dereference.
