Since CSE creates instructions, if we let CSE generate things register
coalescing can't remove, bad things will happen. Only let CSE combine
non-copy load_payloads.
E.g., allow CSE to handle this
load_payload vgrf4+0, vgrf5, vgrf6
but not this
load_payload vgrf4+0, vgrf5+0, vgrf5+1
Patch adds a type check between switch init-expression and case label

Like on Haswell, we need to use 8x4 aligned rectangle primitives for
hierarchical depth buffer resolves and depth clears. See the comments
in brw_blorp.cpp's brw_hiz_op_params() constructor. (The Broadwell
documentation confirms that this is still necessary.)
This patch makes the Broadwell code follow the same behavior as Chad and
Jordan's Gen7 BLORP code. Based on a patch by Topi Pohjolainen.
This fixes es3conform's framebuffer_blit_functionality_scissor_blit
test, with no Piglit regressions.

We only enable HiZ for miplevels which are aligned on 8x4 blocks. When

Previously, we would parse MESA_EXTENSION_OVERRIDE each time a context

during context initialization.

In 25268b93, we added a new environment variable
(INTEL_COMPUTE_SHADER) to allow some constant values to be upgraded
for the ARB_compute_shader extension.
Now, we can look to see if the extension was enabled via the
MESA_EXTENSION_OVERRIDE environment variable.

During the early one_time_init phase of context creation, we
initialize two global gl_extensions structures.
We read the MESA_EXTENSION_OVERRIDE environment variable, and store
positive and negative overrides in two structures:
* struct gl_extensions _mesa_extension_override_enables
* struct gl_extensions _mesa_extension_override_disables
These are filled before the driver initializes extensions and
constants, therefore the driver can make adjustments based on the
desired overrides.
This can be useful during development of a new extension where the
extension is only partially ready. The driver can't actually advertise
support for the extension, but if it sees that the override is set for
the extension, then it can expose more supported parts of the
extension, such as upgrading context constants.

Patch refactors the existing uniform processing so explicit locations
are taken in to account during variable processing. These locations
are temporarily stored in gl_uniform_storage before actual locations
are set.
UNMAPPED_UNIFORM_LOC marks unset location so that we can use 0 as a
valid explicit location.
When locations are set, UniformRemapTable is first populated with
uniforms that have explicit location set (inactive and active ones),
rest are put after explicit location slots.

We've used the LD sampler message for pull constant loads on earlier
hardware for some time, and also were already using it for the FS on
Broadwell. This patch makes us use it for Broadwell VS/GS as well.
I believe that when I wrote this code in 2012, we still used the data
port in some cases, and I somehow neglected to convert it while
rebasing.

(n = 17). Many other applications should benefit similarly: this speeds
up uniform array access in the VS, which is commonly used for skinning
shaders, among other things.
