intel: Fix segfault in intel_texsubimage_tiled_memcpy
The function segfaulted when a game called glTexSubImage2D on a texture
with internalformat/format/type = GL_SLUMINANCE8/GL_BGRA/GL_UNSIGNED_BYTE.
The function only supports MESA_FORMAT_ARGB8888 and returns early if it
detects an unsupported format. Clearly, its detection condition was
insufficient. This patch fixes it to explicity check for
MESA_FORMAT_ARGB8888.
Note: This is a candidate for the 9.0 branch (fixes 413c491).

i965: Do texture swizzling in hardware on Haswell.
Haswell supports EXT_texture_swizzle and legacy DEPTH_TEXTURE_MODE
swizzling by setting SURFACE_STATE entries. This means we don't have to
bake the swizzle settings into the shader code by emitting MOV
instructions, and thus don't have to recompile shaders whenever the
swizzles change.
Unfortunately, we can't handle GL_ALPHA this way: unlike all the others,
which store the comparison result in the .r channel (and possibly others
as well), GL_ALPHA puts it in the .a channel. The GLSL 1.30+ style
functions which return a float always simply return the .r channel,
which would be zero if we handled this as a surface override. In this
case, fall back to doing it the old way. DEPTH_TEXTURE_MODE = GL_ALPHA
isn't an interesting performance path anyway.

GLES 3 supports sRGB functionality, but it does not expose the
GL_FRAMEBUFFER_SRGB enable/disable bit. Instead the implementation
is expected to behave as though that bit is always enabled.
This patch ensures that ctx->Color.sRGBEnabled (the internal variable
tracking GL_FRAMEBUFFER_SRGB) is initially true in GLES 2/3 contexts,
and that it cannot be modified through the GLES 3 API.
This is safe for GLES 2, since ctx->Color.sRGBEnabled has no effect on
non-sRGB formats, and GLES 2 doesn't support any sRGB formats.

meta: Properly save/restore GL_FRAMEBUFFER_SRGB in Meta.
Previously, meta logic was saving and restoring the value of
GL_FRAMEBUFFER_SRGB in an ad-hoc fashion. As a result, it was not
properly disabled and/or restored for some meta operations.
This patch causes GL_FRAMEBUFFER_SRGB to be saved/restored in the
conventional way of meta-ops (using _mesa_meta_begin() and
_mesa_meta_end()). It is now reliably saved/restored for
_mesa_meta_BlitFramebuffer, _mesa_meta_GenerateMipmap, and
decompress_texture_image, and preserved for all other meta ops.

GLES3 supports sRGB formats, but it does not support the

GL_FRAMEBUFFER_SRGB will need a backdoor mechanism to do so when the

intel: Improve teximage perf for Google Chrome paint rects (v3)
This patch reduces the time spent in glTexImage and glTexSubImage by
over 5x on Sandybridge for the workload described below.
It adds a new fast path for glTexImage2D and glTexSubImage2D,
intel_texsubimage_tiled_memcpy, which is optimized for Google Chrome's
paint rectangles. The fast path is implemented only for 2D GL_BGRA
textures for chipsets with a LLC.
=== Performance Analysis ===
Workload description:
Personalize your google.com page with a wallpaper. Start chromium
with flags "--ignore-gpu-blacklist --enable-accelerated-painting
--force-compositing-mode". Start recording with chrome://tracing. Visit
google.com and wait for page to finish rendering. Measure the time spent
by process CrGpuMain in GLES2DecoderImpl::HandleTexImage2D and
HandleTexSubImage2D.

v2:
- Replace check for `intel->gen >= 6` with `intel->has_llc`, per
danvet.
- Fix typo in comment, s/throuh/through/.
- Swap 'before' and 'after' rows in stat table.
v3:
- If the current batch references the bo, then flush batch before mapping
the bo. Found by Chris.
- Restrict supported texture images to level 0 of target
GL_TEXTURE_2D. This avoids an arithmetic bug in calculating image
offsets within the miptree, found by Paul. This restriction does not
diminish this patch's benefit to Chrome OS performance.
- Use less instructions for bit6 swizzling, suggested by Paul.
- Remove erroneous comment about Y-tiling, for Paul.
- Print perf_debug messages when flushing and stalling.
- Update stats in commit message; run workload under a release build
rather than a debug build.

A game we're working with leaves scissoring enabled, but frequently sets

scissoring has no effect, so it's safe to go ahead with a fast clear.
Chad believe this should help with Oliver McFadden's "Dante" as well.

Commit e2249e8c4d (i965/blorp: Add
support for blits between SRGB and linear formats) changed blorp to
always configure surface states for in linear format (even if the
underlying surface is sRGB). This allowed sRGB-to-linear and
linear-to-sRGB blits to occur without causing the image to be
inappropriately brightened or darkened.
However, it broke sRGB MSAA resolves, since they rely on the
destination buffer format being sRGB in order to ensure that samples
are averaged together in sRGB-correct fashion.
This patch fixes the problem by instead configuring the source buffer
to use the *same* format as the destination buffer. This ensures that
the image won't be brightened or darkened, but preserves proper sRGB
averaging.
Fixes piglit tests "EXT_framebuffer_multisample/accuracy srgb".
