2d9e0f24e1 Android: fix x86 gallium builds
Builds with gallium enabled fail on x86 with linker error:

external/mesa3d/src/mesa/vbo/vbo_exec_array.c:127: error: undefined reference to '_mesa_uint_array_min_max'

The problem is sse_minmax.c is not included in the libmesa_st_mesa
library. Since the SSE4.1 files are needed for both libmesa_st_mesa
and libmesa_dricore, move SSE4.1 files into a separate static library
that can be used by both.

cdf7c6b83d gallivm: Use vector selects on LLVM 3.3+.
This is an old patch I had around.

Vector selects seem to work well from LLVM 3.3.  Using them should
improve code quality, as it might make constant propagation pass more
effective.

Tested lp_test_*

cd7d631c71 glsl: do not raise unitialized variable warnings on builtins/reserved GL variables
Needed because not all the built-in variables are marked as system
values, so they still have the mode ir_var_auto. Right now it fixes
raising the warning when gl_GlobalInvocationID and
gl_LocalInvocationIndex are used.

58d4751fa0 i965: Fix textureSize() depth value for 1 layer surfaces on Gen4-6.
According to the Sandybridge PRM's description of the resinfo message,
the .z value returned will be Depth == 0 ? 0 : Depth + 1.  The earlier
PRMs have the same table.

This means we return 0 for array textures with a single slice, when
we ought to return 1.  Just override it to max(depth, 1).

Fixes 10 dEQP-GLES3.functional tests on Sandybridge:
shaders.texture_functions.texturesize.sampler2darray_fixed_vertex

08ff5f4d1f nir: Simplify a bcsel to logical-or
Oddly, this did not affect the shader where I first noticed the pattern.
That particular shader doesn't get its if-statement converted to a bcsel
because there are two assignments in the else-statement.  This led to me
submitting https://bugs.freedesktop.org/show_bug.cgi?id=94747.

checking that the returned indexes matched.

f96a403bc3 nv50/ir: Check for valid insn instead of def size
This fixes a null pointer dereference during the register allocation pass,
if a function had arguments.

Functions arguments get a definition from the function itself, a definition
which is therefore not linked to any instruction. If a value ends up having
a definition but no linked instruction, the register allocation pass doesn't
need to consider whether that value is generated by an instruction that
can only handle "short" registers (on nv50).

436bdd7403 Revert "i965: Don't add barrier deps for FB write messages."
This reverts commit d0e1d6b7e2.

The change in the vec4 code is a mistake -- there's never an
FS_OPCODE_FB_WRITE in vec4 code.

The change in the fs code had the (harmless) effect of not recognizing
an FB_WRITE as a scheduling barrier even if it was marked EOT --
harmless because the scheduler marked the last instruction of a block as
a barrier, something I'm changing in the following patches.

This will be reimplemented later in the series.

    When no *xfb_stride* is specified for a buffer, the stride of a
    buffer will be the smallest needed to hold the variable placed at
    the highest offset, including any required padding."

8120e869b1 glsl: validate global out xfb_stride qualifiers and set stride on empty buffers
Here we use the built-in validation in
ast_layout_expression::process_qualifier_constant() to check for mismatching
global out strides on buffers in a single shader.

From the ARB_enhanced_layouts spec:

   "While *xfb_stride* can be declared multiple times for the same buffer,
   it is a compile-time or link-time error to have different values
   specified for the stride for the same buffer."

For intrastage validation a new helper link_xfb_stride_layout_qualifiers()
is created. We also take this opportunity to make sure stride is at least
a multiple of 4, we will validate doubles at a later stage.

From the ARB_enhanced_layouts spec:

   "If the buffer is capturing any double-typed outputs, the stride must
   be a multiple of 8, otherwise it must be a multiple of 4, or a
   compile-time or link-time error results."

Finally we update store_tfeedback_info() to apply the strides to
LinkedTransformFeedback and update the buffers bitmask to mark any global
buffers with a stride as active. For example a shader with:

layout (xfb_buffer = 0, xfb_offset = 0)  out vec4 gs_fs;
layout (xfb_buffer = 1, xfb_stride = 64) out;

Is expected to have a buffer bound to both 0 and 1.

From the ARB_enhanced_layouts spec:

   "A binding point requires a bound buffer object if and only if its
   associated stride in the program object used for transform feedback
   primitive capture is non-zero."
