mesa: add PROGRAM_IMMEDIATE, PROGRAM_BUFFER

This makes PROGRAM_IMMEDIATE a first-class gl_register_file type, and
adds PROGRAM_BUFFER to the list. These are used purely inside

glsl: keep track of ssbo variable being accessed, add access params

Currently any access params (coherent/volatile/restrict) are being lost
when lowering to the ssbo load/store intrinsics. Keep track of the
variable being used, and bake its access params in as the last arg of
the load/store intrinsics.

If the variable is accessed via an instance block, then 'variable'
points to the instance block variable and not the field inside the
instance block that we are accessing. In order to check access
parameters for the field itself we need to detect this case and keep
track of the corresponding field struct so we can extract the specific
field access information from there instead.

i965: Implement a drirc workaround for broken dual color blending.

OpenGL's dual color blending feature was specified so that an
implementation could support both multiple render targets (MRT) and
dual source blending.  Fragment shader outputs specify both "location"
(the render target number) and "index" (either color 0 or 1).

I believe DirectX only has the notion of "location" - if using dual
color blending, location 0 or 1 will specify the operands.  If not,
then location means the render target index.  The two features can't
be used together.

As such, some applications mistakenly try to use <loc = 0, index = 0>
and <loc = 1, index = 0> in a shader used for dual color blending with
a single render target, rather than the correct <loc = 0, index = 0>
and <loc = 0, index = 1>.

In particular, Unigine Heaven 4.0 and Valley 1.0 suffer from this bug.
Unigine is aware of the problem, and quickly developed a fix, but has
not bothered to change the download link on their website to a working
copy in over a year.  People were still using the broken version and
complaining.  We tried working around this by disabling dual color
blending, but that apparently hurts performance, and people were once
again unhappy.

On i965, dual source blending is achieved by using different framebuffer
write messages than normal rendering.  So, we have to compile different
code for the two cases.  We're not being pedantic: we actually have to
know in order to function.

Normally, dual source blending is detectable in the shader: if a shader
has an output with index = 1, then it's meant for blending, not MRT.
With the broken inputs, they're indistinguishable, so we can only tell
by looking at the current GL state.

This patch implements a new drirc workaround:

   export dual_color_blend_by_location=true

which makes the i965 driver detect when OpenGL state is configured for
dual source blending, and recompile the fragment shader to use the right
messages.  In that case, we allow either location = 1 or index = 1 to
specify the second source for the blending equations.

It also re-enables GL_ARB_blend_func_extended for Unigine.

Revert "radeonsi: fix discard-only fragment shaders (v2)"

This reverts commit 843855bbf0da2204ce536623ba957bfa83fdbd52.

It became redundant due to Marek's earlier pushed 8667a1ae which achieves
the same thing.

radeonsi: fix discard-only fragment shaders (v2)

When a fragment shader is used that has no outputs but does conditional
discard (KILL_IF), all fragments are killed without this patch.

By comparing various register settings, my conclusion is that the exec mask
is either not properly forwarded to the DB by NULL exports or ends up being
unused, at least when there is _only_ a NULL export (the ISA documentation
claims that NULL exports can be used to override a previously exported exec
mask).

Of the various approaches I have tried to work around the problem, this one
seems to be the least invasive one.

glapi: Build glapi_gentable.c only on Darwin

Removes the public symbol _glapi_create_table_from_handle from
libGL.so.1.2.0 on all platforms except Darwin.

Since the symbol is not used on other platforms it makes sense to
build glapi_gentable.c only on Darwin.

As a side effect it accelerates the build a bit and reduces the size
of libGL.so.1.2.0 as follows:

size lib/libGL.so.1.2.0 on my system shows
   text    data     bss     dec     hex filename
 469211   21848    2720  493779   788d3 lib/libGL.so.1.2.0 before
 420988   11240    2720  434948   6a304 lib/libGL.so.1.2.0 after
