i965/fs: Assert that the number of color targets is one when dual-source blend is enabled.

Requested by Anuj during review of
4a87e4ade778e56d43333c65a58752b15a00ce69, adding as follow-up since it
led to assertion failures due to various GLSL bugs that should be
fixed now.

glsl: Fix gl_program::OutputsWritten computation for dual-source blending.

In the fragment shader OutputsWritten is a bitset of FRAG_RESULT_*
enumerants, which represent the location of each color output written
by the shader.  The secondary and primary color outputs of a given
render target using dual-source blending have the same location, so
the 'idx' computation below will give the wrong bit as result if the
'var->data.index' term is non-zero -- E.g. if the shader writes the
primary and secondary colors of the FRAG_RESULT_COLOR output,
ir_set_program_inouts will think that the shader writes both
FRAG_RESULT_COLOR and FRAG_RESULT_SAMPLE_MASK, which is just bogus.

That would cause the brw_wm_prog_key::nr_color_regions computation
done in the i965 driver during fragment shader precompilation to be
wrong, which currently leads to unnecessary recompilation of shaders
that use dual-source blending, and triggers an assertion failure in
fs_visitor::emit_fb_writes() on my i965-fb-fetch branch.

glsl: Fix incorrect hard-coded location of the gl_SecondaryFragColorEXT built-in.

gl_SecondaryFragColorEXT should have the same location as gl_FragColor
for the secondary fragment color to be replicated to all fragment
outputs.  The incorrect location of gl_SecondaryFragColorEXT would
cause the linker to mark both FRAG_RESULT_COLOR and FRAG_RESULT_DATA0
as being written to, which isn't allowed by the spec and would
ultimately lead to an assertion failure in
fs_visitor::emit_fb_writes() on my i965-fb-fetch branch.

This should also fix the code below for multiple dual-source-blended
render targets, which no driver currently supports but we have plans
to enable eventually in the i965 driver (the comment saying that no
hardware will ever support it seems rather hilarious).

st/glsl_to_tgsi: Use SecondaryOutputsWritten to determine dual-source fragment outputs.

Currently the mesa state tracker relies on there being two bits set
per dual-source output in the gl_program::OutputsWritten bitset, but
that only worked due to a GLSL front-end bug that caused it to set the
OutputsWritten bit for both location and location+1 even though at the
GLSL level the primary and secondary color outputs used for
dual-source blending have the same location.  Fix it by extending
outputMapping[] to 2*FRAG_RESULT_MAX elements in order to represent a
mapping from a (location, index) pair to its TGSI output, which should
also make it slightly easier to add support for dual-source blending
in combination with multiple render targets in the long run.

anv: Rework pipeline caching

The original pipeline cache the Kristian wrote was based on a now-false
premise that the shaders can be stored in the pipeline cache.  The Vulkan
1.0 spec explicitly states that the pipeline cache object is transiant and
you are allowed to delete it after using it to create a pipeline with no
ill effects.  As nice as Kristian's design was, it doesn't jive with the
expectation provided by the Vulkan spec.

The new pipeline cache uses reference-counted anv_shader_bin objects that
are backed by a large state pool.  The cache itself is just a hash table
mapping keys hashes to anv_shader_bin objects.  This has the added
advantage of removing one more hand-rolled hash table from mesa.

as well as all of the metadata that is generated at shader compile time.
The struct is very similar to the old cache_entry struct except that it
is reference counted and stores the actual pipeline_bind_map.  Similarly to
cache_entry, much of the actual data is floating-size and stored after the
main struct.  Unlike cache_entry, which was storred in GPU-accessable
memory, the storage for anv_shader_bin kernels comes from a state pool.
The struct itself is reference-counted so that it can be used by multiple
pipelines at a time without fear of allocation issues.

svga: fix a texture readback bug

Backing views/surfaces are used to handle the case when a resource is
bound both as a render target and as a sampler source (such as when
doing auto mipmap generation).

This patch fixes a bug where mapping a resource (to do a glReadPixels)
was reading the stale data in the original surface rather than the
backing surface which was rendered to.

We need to propagate the backing resource (which we rendered to) back
to the original resource before we read from it.  The problem was the
svga_propagate_rendertargets() function was examining the wrong surface
views.
