Both intel_context.h and brw_defines.h have #defines for comparison

They're exactly the same values, so it makes sense to pick one.

Commit cf31a19300 removed support for BOs
backed by system memory, as it was only useful for i915. However, it
removed a little too much code: intel_bufferobj_buffer() used to call
intel_bufferobj_alloc_buffer(), and after that commit, it didn't.
This led to NULL pointer dereferences in several test cases, such as
es3conform's transform_feedback_state_variables test.
This commit restores the allocation, preserving the original behavior.
It may not be the cleanest approach, but tidying should come later.

This ensures that inter-shader outputs and inputs are properly eliminated
across 3 or more shader stages. The behavior is unchanged with 2 or less
shader stages.
For example, elimination of unused FS inputs causes elimination of matching
GS outputs, which causes elimination of the GS inputs that were needed for
evaluation of the eliminated GS outputs, which causes elimination of
matching VS outputs. An unused FS input is all that's needed to trigger
this chain reaction.

This patch adds texture() for isamplerCubeArray and usamplerCubeArray,
which were entirely missing.
It also makes texture() with a LOD bias fragment shader specific. The
main GLSL specification explicitly says that texturing with LOD bias
should not be allowed for vertex shaders.
Affects Piglit's ARB_texture_cube_map_array/compiler/tex_bias-01.vert.
which tries to use bias in a vertex shader. Currently, it expects this
to pass (so this patch regresses the test), but I've sent a patch to
reverse the expected behavior (so this patch would fix the updated test):

Current implementation of ext_framebuffer_multisample_blit_scaled in
i965/blorp uses nearest filtering for multisample scaled blits. Using
nearest filtering produces blocky artifacts and negates the benefits
of MSAA. That is the reason why extension was not enabled on i965.
This patch implements the bilinear filtering of samples in blorp engine.
Images generated with this patch are free from blocky artifacts and show
big improvement in visual quality.
Observed no piglit and gles3 regressions.
V3:
- Algorithm used for filtering assumes a rectangular grid of samples
roughly corresponding to sample locations.
- Test the boundary conditions on the edges of texture.
V4:
- Clip texcoords and use conditional MOVs.
- Send texture dimensions as push constants.
- Remove the optimization in case of scaled multisample blits.
V5:
- Move mcs_fetch() inside the 'for' loop after computing pixel coordinates.

We were incorrectly computing the buffer offset when using the
instances. The buffer offset is always equal to:
start_instance * stride + (instance_num / instance_divisor) *
stride
We were completely ignoring the start instance quite
often producing instances that completely wrong, e.g. if
start instance = 5, instance divisor = 2, then on the first
iteration it should be:
5 * stride, not (5/2) * stride as we'd have currently, and if
start instance = 1, instance divisor = 3, then on the first
iteration it should be:
1 * stride, not 0 as we'd have.
This fixes it and adjusts all the code to the changes.

We weren't taking into account the size of element
that is to be fetched, which meant that it was possible
to overflow the buffer reads if the stride was very
close to the end of the buffer, e.g. stride = 3, buffer
size = 4, and the element to be read = 4. This should
be properly detected as an overflow.
