Framebuffers can have NULL attachments since a while. llvmpipe handled
that properly for lp_rast_shade_quads_mask but it seems the change didn't
make it to lp_rast_shade_tile.
This fixes piglit fbo-drawbuffers-none test (though I need to increase

(cherry picked from commit eb2241f8a9)
The glGetGraphicsResetStatusARB from ARB_robustness extension always
returns GUILTY_CONTEXT_RESET_ARB and never returns NO_ERROR for guilty
context with LOSE_CONTEXT_ON_RESET_ARB strategy. This is because Mesa
returns GUILTY_CONTEXT_RESET_ARB if batch_active !=0 whereas kernel
driver never reset batch_active and this variable always > 0 for guilty
context. The same behaviour also can be observed for batch_pending and
INNOCENT_CONTEXT_RESET_ARB.
But ARB_robustness spec says:
If a reset status other than NO_ERROR is returned and subsequent calls
return NO_ERROR, the context reset was encountered and completed. If a
reset status is repeatedly returned, the context may be in the process
of resetting.
8. How should the application react to a reset context event?
RESOLVED: For this extension, the application is expected to query the
reset status until NO_ERROR is returned. If a reset is encountered, at
least one *RESET* status will be returned. Once NO_ERROR is
encountered, the application can safely destroy the old context and
create a new one.
The main problem is the context may be in the process of resetting and
in this case a reset status should be repeatedly returned. But looks
like the kernel driver returns nonzero active/pending only if the
context reset has already been encountered and completed. For this
reason the *RESET* status cannot be repeatedly returned and should be
returned only once.
The reset_count and brw->reset_count variables can be used to control
that glGetGraphicsResetStatusARB returns *RESET* status only once for
each context. Note the i915 triggers reset_count twice which allows to
return correct reset count immediately after active/pending have been
incremented.
v2 (idr): Trivial reformatting of comments.

Retrieving the high 32 bits of a signed multiply is rather annoying. It
appears that the simplest way to do this is to compute the absolute
value of the arguments, and perform a u32 x u32 -> u64 operation. If the
arguments' signs differ, then negate the result. Since there is no u64
support in the cvt instruction, we have the perform the 2's complement
negation "by hand".
This logic can come into use by the IMUL_HI instruction (very unlikely
to be seen), as well as from constant folding of division by a constant.
Fixes dolphin's divisions by 255.

UNION appears to expect that all of its sources are conditionally

much less directly, unsigned integer division by a constant, which uses
this functionality in a peephole pass.

The first was apparently not entirely suitable for stable, (and buggy). And
the second existed only to fix a bug in the first. So without the first, we
don't need either.
We allocate dispatch tables for BeginEnd and OutsideBeginEnd. But
when we destroy the context we were freeing the BeginEnd and Exec
tables. If Exec==BeginEnd we did a double-free. This would happen
if the context was destroyed while inside a glBegin/End pair. Now
free the BeginEnd and OutsideBeginEnd pointers.
