The key for a geometry shader would be interpreted as the key for a vertex
shader further down the line, which really doesn't make sense.
This does not affect the contents of shader->key because geometry shaders
don't have any key entries anyway.

Specifically, when the API switches from using a GS to not using a GS and then
back to using the same GS again, we do not have to re-send all the GS state,
but we do have to send VGT_GS_MODE. So make VGT_GS_MODE consistently be a part
of the VS state.
This fixes a rendering bug in Dolphin, but surely other applications are
affected as well.

This reverts commit 67e3098703.
It breaks a bunch of geometry shader tests, such as "spec@!opengl 3.2@minmax"
and others depending on the glGet queries.
In the old hand-writen implementation of atan2, the calculation of
atan(y/x) was performed conditionally in the "then" block of the
outermost if statement. I believe I accidentally lifted this out
into unconditional code when converting to IR builder.
For reference, the original hand-written IR is visible in commit
722eff674b.

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.

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.
v2: take discard by alpha test into account as well

Normally there's a producer and consumer, and the producer var gets
picked. In both the vertex->gs and tes->gs cases, that's the un-arrayed
version.
In the SSO case, however, there is no producer. So we picked the arrayed
GS variable, and as a result, used more slots than we should. More
critically, these slots would also no longer line up with the producer's
calculation. To fix this, we need to fix up the type of the variable
based on stage no matter what.

By using whole static libraries the android buildsystem provides
whole-archive (alike) solution. This means that we don't need to worry
about the order of the static libraries and any reverse, recursive or
circular dependencies that they have between one another.
Without this the linker will discard any unused hunks of one library
and we'll end up with unresolved symbols as those are required by
another static library. This issue has become more prominent with the
introduction of pipe-loader.
Whole static libraries has been used in i915/i965 for a very long

The commit b4e198f47f changed the offset and bits parameters of the
bitfield insert operation from scalars to vectors. However, the lowering
of ldexp on doubles operates on each vector component and emits scalar
code (since it has to deal with the lower and upper 32-bit chunks of
each double component), so it needs its bits and offset parameters to
be scalars.
