We use 128bit vector interleave for untwiddling in the blend code (with
256bit vectors). llvm generates terrible code for this for some reason,
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.
(The generated code is still not terribly good as we could actually avoid
the interleaving completely but llvm can't know this.)

Probably due to CRLF endings, the discovery of python import statements
was not working on Windows builds, causing incremental builds to often
fail unless one wiped out the build directory.
NOTE: This is a candidate for stable branches.
We flush pending rendering before running CopySubBuffer, which
ensures that the right bits get to the screen.

Just like we produce from inside the Intel driver, this can help provide
information quickly about FBO incompatibility problems (particularly when
using apitrace replay).
Currently, in driver-marked incompleteness cases, you'll get both the
driver message and the core message on Intel. Until the other drivers are
fixed to produce output, I think this is better than not putting in a
message for driver-marked incomplete.

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.

The patch that follows will fix a bug that prevents
intel_flush_front() from being called often enough. In doing so, it
will create a situation where intel_flush_front() is called during the
initial call to glXMakeCurrent(). In this circumstance,
ctx->DrawBuffer hasn't been initialized yet and is NULL. Fortunately,
intel->front_buffer_dirty is false, so intel_flush_front() doesn't
actually need to do anything. To avoid a segfault, swap the order of
terms in intel_flush_front()'s if statement.

piglit OpenGL ES 3.0/minmax now passes. This was also one of the subcase

Mostly just make sure the layer parameter gets passed through to the right
places (and get clamped, can do this at setup time), fix up clears to
clear all layers and disable opaque optimization. Luckily don't need to
touch the jitted code.
(Clears invoked via pipe's clear_render_target method will not work however
since the pipe_util_clear function used for it doesn't handle clearing
multiple layers yet.)
v2: per Brian's suggestion, prettify var initialization and add some comments,
add assertion for impossible layer specification for surface.

Introduce ilo_surface_cso and initialize it in create_surface(). With the
change, we can emit SURFACE_STATE directly from the CSO and remove
emit_surf_SURFACE_STATE(). We do not deal with depth/stencil surfaces yet.
Introduce ilo_cbuf_cso and initialize it in set_constant_buffer(). As
ilo_view_surface is embedded in ilo_cbuf_cso, switch to emit_SURFACE_STATE()
for constant buffers and remove emit_cbuf_SURFACE_STATE().
Introduce ilo_view_cso and initialize it in create_sampler_view(). Add
emit_SURFACE_STATE() to GPE, which can emit SURFACE_STATE from
ilo_view_surface.
