llvmpipe: fix a bug in opaque optimization

If there are queries active the opaque optimization reseting the bin needs to
be disabled.
(Not really tested since the bug was discovered by code inspection not
an actual test failure.)

llvmpipe: remove never reached code for timestamp queries.

timestamp queries are always binned in an active scene, therefore
always have a result.
llvmpipe: handle offset_clamp

This was just ignored (unless for some reason like unfilled polys draw was
handling this).
I'm not convinced of that code, putting the float for the clamp in the key
isn't really a good idea. Then again the other floats for depth bias are
already in there too anyway (should probably have a jit_context for the
setup function), so this is just a quick fix.
Also, the "minimum resolvable depth difference" used isn't really right as it
should be calculated according to the z values of the current primitive
and not be a constant (of course, this only makes a difference for float
depth buffers), at least for d3d10, so depth biasing is still not quite right.

i965,i915: Return early if miptree allocation fails

If allocation fails in intel_miptree_create_layout(), don't proceed to
dereference the miptree. Return an early NULL.

Fixes static analysis error reported by Klocwork.

Note: This is a candidate for the 9.1 branch.
