gallium: turn PIPE_SHADER_CAP_DOUBLES into a screen capability

Make the cap consistent with PIPE_CAP_INT64.

Aside from the hypothetical case of using draw for vertex shaders (and
actually caring about doubles...), every implementation supports doubles
either nowhere or everywhere.

Also, st/mesa didn't even check the cap correctly in all supported
shader stages.

While at it, add a missing LLVM version check for 64-bit integers in
radeonsi. This is conservative: judging by the log, LLVM 3.8 might be
sufficient, but there are probably bugs that have been fixed since then.

mesa: Enable EXT_compressed_ETC1_RGB8_sub_texture

Since we already have the functionality in place and games
like Game of Thrones seem to depend on this extension, I
think it makes sense to enable it by making it part of

https://www.khronos.org/registry/gles/extensions/EXT/EXT_compressed_ETC1_RGB8_sub_texture.txt

Note: OES_compressed_ETC1_RGB8_sub_texture seems to be listed
in gl2ext.h, but there's no documentation for it in the KHR
registry

anv: always allocate a vertex element with vertexid or instanceid

Up to now on Gen8+ we only allocated a vertex element for
gl_InstanceIndex or gl_VertexIndex when a vertex shader uses
gl_BaseInstanceARB or gl_BaseVertexARB. This is because we would
configure the VF_SGVS packet to make the VF unit write the
gl_InstanceIndex & gl_VertexIndex values right behind the values
computed from the vertex buffers.

In the next commit we will also write the gl_DrawIDARB value. Our
backend expects to pull the gl_DrawIDARB value from the element
following the element containing gl_InstanceIndex, gl_VertexIndex,
gl_BaseInstanceARB and gl_BaseVertexARB (see
vec4_vs_visitor::setup_attributes). Therefore we need to allocate an
element for the SGVS elements as long as at least one of the SGVS
element is read by the shader. Otherwise our shader will use a
gl_DrawIDARB value pulled from the URB one element too far (most
likely garbage).

anv: Improve flushing around STATE_BASE_ADDRESS

It is not clear from the docs exactly how pipelined STATE_BASE_ADDRESS
actually is.  We know from experimentation that we need to flush the
render cache prior to emitting STATE_BASE_ADDRESS and invalidate the
texture cache afterwards.  The only thing the PRM says is that, on gen8+
we're supposed to invalidate the state cache after STATE_BASE_ADDRESS
but experimentation has indicated that doing so does nothing whatsoever.

Since we don't really know, let's do just a bit more flushing in the
hopes that this won't be a problem again.  In particular:

 1) Do a CS stall before we emit STATE_BASE_ADDRESS since we don't
    really know whether or not it's pipelined.

 2) Do a data cache flush in case what runs before STATE_BASE_ADDRESS
    is a compute shader.

 3) Invalidate the state and constant caches after STATE_BASE_ADDRESS
    because the state may be getting cached there (we don't really know).
