i965/fs: Implement lowering of logical framebuffer writes.
This does essentially the same thing as
fs_visitor::emit_single_fb_write(), with some slight differences:
- We don't have to worry about exec_size and use_2nd_half anymore,
16-wide sources have already been lowered to 8-wide thanks to the
previous commit and the manual argument unzipping is no longer
required.
- The src/dst_depth and sample_mask values are now explicit sources
of the instruction instead of being taken from the visitor state
directly. The same goes for the kill-pixel mask that will be
passed to the instruction explicitly as predicate.
- Everything is now done in static functions to improve
encapsulation.

There's no need to initialize the wrong half of oMask in the payload
when we're doing an 8-wide framebuffer write because it will be
ignored by the hardware anyway. By doing it this way we can let the
SIMD lowering pass split the sample_mask source as a regular
per-channel source, otherwise we would have to introduce some sort of
per-instruction source query or use fs_inst::header_size for the
lowering pass to be able to find out whether some source is
header-like, and leave the source untouched in that case.
As a bonus this achieves the same purpose as the previous code without
making use of the SET_OMASK pseudo-instruction, which will be removed

patch will cause code like the following to be emitted:
MOV(16) tmp<1>:uw, src
MOV(8) dst<1>:ud, tmp<8,8,1>:ud
The second MOV comes from the expansion of a LOAD_PAYLOAD header copy,

turn this into:
MOV(8) dst<1>:ud, src
Which has different semantics. Fix it by preventing propagation in
cases where a single channel of the instruction would span several
channels of the copy (this requirement could in fact be relaxed if the
copy is just a trivial memcpy, but this case is unusual enough that I
don't think it matters in practice).

i965/fs: Implement pass to lower instructions of unsupported SIMD width.
This lowering pass implements an algorithm to expand SIMDN
instructions into a sequence of SIMDM instructions in cases where the
hardware doesn't support the original execution size natively for some
particular instruction. The most important use-cases are:
- Lowering send message instructions that don't support SIMD16
natively into SIMD8 (several texturing, framebuffer write and typed
surface operations).
- Lowering messages that don't support SIMD8 natively into SIMD16
(*cough*gen4*cough*).
- 64-bit precision operations (e.g. FP64 and 64-bit integer
multiplication).
- SIMD32.
The algorithm works by splitting the sources of the original
instruction into chunks of width appropriate for the lowered
instructions, and then interleaving the results component-wise into
the destination of the original instruction. The pass is controlled
by the get_lowered_simd_width() function that currently just returns
the original execution size making the whole pass a no-op for the
moment until some user is introduced.

egl: Add support for DRM_FORMAT_R8, RG88, and GR88
The Kodi/XBMC developers want to transcode NV12 to RGB with OpenGL shaders,
importing the two source planes through EGL_EXT_image_dma_buf_import. That
requires importing the Y plane as an R8 EGLImage and the UV plane as either an
RG88 or GR88 EGLImage.
This patch teaches the driver-independent part of EGL about the new
formats. Real driver support is left for follow-up patches.
The new formats landed in airlied's kernel branch 'drm-next' on July 24.
