r600g: upsample and downsample MSAA resources for transfers
We did downsample (=resolve) MSAA resources to make ReadPixels work with MSAA
GLX visuals, which was enough for read-only color-only transfers.
This commit makes write color transfers and depth-stencil transfers work
in a similar manner. It does downsampling in transfer_map and upsampling
in transfer_unmap.

glsl: Generate smaller values for uniform locations
Previously we would generate uniform locations as (slot << 16) +

of a[2] will be +1 from the location of a[1]. This resulted in every
uniform location being at least 0x10000. The OpenGL 4.3 spec was
amended to require this behavior, but previous versions did not require
locations of array (or structure) members be sequential.
We've now encountered two applications that assume uniform values will
be "small." As far as we can tell, these applications store the GLint
returned by glGetUniformLocation in a int16_t or possibly an int8_t.
THIS BEHAVIOR IS NOT GUARANTEED OR IMPLIED BY ANY VERSION OF OpenGL.

This happens, for instance, when an extension like GL_OES_EGL_image or
GLX_EXT_texture_from_pixmap extension is used to associate a miptree
with an image existing outside of Mesa.
When this happens, we need to disable fast color clears on the miptree
in question, since there's no good synchronization mechanism to ensure
that deferred clear writes get performed by the time the buffer is
examined from the other miptree, or from outside of Mesa.
Fortunately, this should not be a performance hit for most
applications, since most applications that use these extensions use
them for importing textures into Mesa, rather than for exporting
rendered images out of Mesa. So most of the time the miptrees
involved will never experience a clear.

This is rather cumbersome: it requires two state atoms instead of one,
and there's a strict ordering dependency in the list. Plus, the code
gets spread across two functions (or even files in the case of Gen7+).
Gen7+ has a packet to update just the blend state pointer, so it makes a
lot of sense to simply emit that right away. Gen6 has a combined packet
which updates blending, the color calculator, and depth/stencil state;
however, each can still be modified independently.
This drops the Gen6 micro-optimization where we tried to only emit one
packet that changed all three states. State updates are pretty cheap.

This fixes some rendering issues for a gnome session on System z.
It also fixes various piglit tests on z, such as
spec/ARB_color_buffer_float/GL_RGBA8-render.
The patch deliberately doesn't tackle the more complicated
SNORM case.
Tested against piglit on x86_64 and System z with no regressions.

intel: Reserve less batchbuffer space.
Now that Gen6+ relies on hardware contexts, we don't need to record an
occlusion query value at the end of each batch. That means we no longer
need to reserve space for the absurd number of PIPE_CONTROLs required to
do that on Sandybridge.

The adreno a3xx GPU is found in newer snapdragon devices, such as the

Compared to a2xx, it introduces an entirely new unified shader ISA, and
re-shuffles all or nearly all of the registers. The good news is that
(for the most part) the registers are more orthogonal, not combining
unrelated state in a single register. And that there is a lot more
flexibility, so we don't need to patch and re-emit the shader like we
did on a2xx.
The shader compiler is currently quite dumb, there would be a lot of
room for improvement with an optimizing pass. Despite that, with the

gallivm: work around slow code generated for interleaving 128bit vectors
We use 128bit vector interleave for untwiddling in the blend code (with

so instead of generating a shuffle for 2 128bit vectors use a
extract/insert shuffle instead (it only seems to matter we're not using
128bit wide vectors for the shuffle). This decreases instruction count of
the blend code generated for a rgba8 render target without blending from
169 to 113 with llvm 3.1 and from 136 to 114 in llvm 3.2/3.3, and I got
a ~8% (llvm 3.1) and ~5% (3.2/3.3) performance improvement in gears.

intel: flush fake front buffer more robustly.
When a fake front buffer is in use, if we request the front buffer
(using screen->dri2.loader->getBuffersWithFormat()), the X server
copies the real front buffer to the fake front buffer and returns the
fake front buffer. We sometimes make redundant requests for the front
buffer (due to using a single counter to track invalidates for both
the front and back buffers), so there's a danger of pending front
buffer rendering getting overwritten when the redundant front buffer
request occurs.
Previous to this patch, intel_update_renderbuffers() worked around
that problem by sometimes doing intel_flush() and intel_flush_front()
before calling intel_query_dri2_buffers(). But it only did the
workaround when the front buffer was bound for drawing; it didn't do
it when the front buffer was bound for reading.
This patch moves the workaround code to intel_query_dri2_buffers(), so
that it happens in exactly the circumstances where it is needed.
This should fix some of the sporadic failures in Piglit tests
fbo-sys-blit and fbo-sys-sub-blit.
