This just tells the state tracker to turn on the GL_ARB_shader_texture_lod
extension. This simply allows the GLSL compiler to emit TXL and TXD
instructions for both vertex and fragment shaders. We already support
these opcodes in the svga driver. Though, the shadow2DGrad() Piglit
tests are failing.

With this patch, the llvmpipe and draw modules will calculate the depth bias
according to floating point depth buffer semantics described in the
arb_depth_buffer_float specification, when the driver has a z buffer bound
with a format type of UTIL_FORMAT_TYPE_FLOAT.
By default, the driver will use the existing UNORM calculation for depth bias.
A new function, draw_set_zs_format, was added to calculate the Minimum
Resolvable Depth value and floating point depth sense for the draw module.

This brings over the batch-wrap-prevention and aperture space checking
code from the normal brw_draw.c path, so that we don't need to flush the
batch every time.
There's a risk here if the intel_emit_post_sync_nonzero_flush() call isn't
high enough up in the state emit sequences -- before, we implicitly had
one at the batch flush before any state was emitted, so Mesa's workaround
emits didn't really matter. Since the SNB fixes by Ken, I didn't see any
regressions after 3 piglit runs.

The two apps that are hurt happen to include stalls on busy buffer

flush.

Currently, has_surface_tile_offset is equivalent to gen == 4 && !is_g4x.
We already use it for related checks in brw_wm_surface_state.c, so it
makes sense to use it here too. It's simpler and more future-proof.
Broadwell also lacks surface tile offsets. With this patch, I won't
need to update any generation checking; I can simply not set the flag.
