nv50/ir: fix false global CSE on instructions with multiple defs

If an instruction has multiple defs, we have to do a lot more checks to
make sure that we can move it forward. Among other things, various code
likes to do

    a, b = tex()
    if () c = a
    else c = b

which means that a single phi node will have results pointing at the
same instruction. We obviously can't propagate the tex in this case, but
properly accounting for this situation is tricky. Just don't try for
instructions with multiple defs.

This fixes about 20 shaders in shader-db, including the dolphin efb2ram

This makes arb_clear_buffer_object-unaligned pass on both nv50 and nvc0.

i965/bxt: Fix conservative wm thread counts.

When setting the conservative thread counts, I halved everything. That isn't
correct for the wm, which has nothing to do with actual thread counts. I suck.

BXT only has 1 slice, and there is some ambiguity about subslices, so just
reserve the max possible for now. It looks like this might fix:
piglit.spec.glsl-1_50.execution.variable-indexing.gs-output-array-vec4-index-wr.bxtm64.
I kind of question why that is, but it is what Jenkins says.

Mark is current running some of the other blacklisted tests on this patch. (it
effects anything requiring scratch space).

meta: Use internal functions to set texture parameters

_mesa_texture_parameteriv is used because (the more obvious)
_mesa_texture_parameteri just stuffs the parameter in an array and calls
_mesa_texture_parameteriv.  This just cuts out the middleman.

As a side bonus we no longer need check that ARB_stencil_texturing is
supported.  The test doesn't allow non-supporting implementations to
avoid any work, and it's redundant with the value-changed test.

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.

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.
