mesa currently returns 4 when GL_VERTEX_ATTRIB_ARRAY_SIZE is queried
for a vertex array initially set up with size=GL_BGRA. This patch
makes changes to return size=GL_BGRA as required by the spec.

For graphics, the LLVM compiler backend currently has many shortcomings
compared to the non-LLVM one. E.g. it can't handle geometry shaders yet,
but that's just the tip of the iceberg.
So building Mesa with --enable-r600-llvm-compiler is currently not
recommended for anyone who doesn't want to work on fixing those issues.
However, for protection of users who end up enabling it anyway for some
reason, let's disable the LLVM backend at runtime by default. It can be
enabled with the environment variable R600_DEBUG=llvm.

This reverts commit a45a50a4828e1357e9555474bc127c5585b3a420.
Unfortunately gcc dumps argv[0] as the first word of --version, so it is
unreliable for detecting gcc.
In particular `cc --version` and `i686-w64-mingw32-gcc --version` give
wrong results.
A better solution needs to be found -- most likely using C-preprocessing
like autotools does. Revert for now.

Currently we can have name space collisions between blocks that define the same
fields. For example:
in block
{
vec4 Color;
} In[];
out block
{
vec4 Color;
} Out;
These two blocks will assign the same interface name (block.Color) to the Color
field in flatten_named_interface_blocks_declarations.cpp, leading to havoc.
This was breaking badly the gl-320-primitive-shading test from ogl-samples.
The patch uses the block instance name to avoid collisions, producing names
like block.In.Color and block.Out.Color to avoid the name clash.

This manifested as rendering failures or sometimes GPU hangs in
compositors when they accidentally got MSAA visuals due to a bug in the X
Server. Today we decided that the problem in compositors was equivalent
to a corruption bug we'd noticed recently in resizing MSAA-visual
glxgears, and debugging got a lot easier.
When we allocate our MCS MT, libdrm takes the size we request, aligns it
to Y tile size (blowing it up from 300x300=900000 bytes to 384*320=122880
bytes, 30 pages), then puts it into a power-of-two-sized BO (131072 bytes,
32 pages). Because it's Y tiled, we attach a 384-byte-stride fence to it.
When we memset by the BO size in Mesa, between bytes 122880 and 131072 the
data gets stored to the first 20 or so scanlines of each of the 3 tiled
pages in that row, even though only 2 of those pages were allocated by
libdrm. In the glxgears case, the missing 3rd page happened to
consistently be the static VBO that got mapped right after the first MCS
allocation, so corruption only appeared once window resize made us throw
out the old MCS and then allocate the same BO to back the new MCS.
Instead, just memset the amount of data we actually asked libdrm to
allocate for, which will be smaller (more efficient) and not overrun.
Thanks go to Kenneth for doing most of the hard debugging to eliminate a
lot of the search space for the bug.

You'll note from the previous commits that there's something of a loop
here: You call CTSI, which calls BlitFB, then if things go wrong that
falls back to CTSI. As a result, meta CTSI reaches over into blitfb to
tell it "no, don't try that fallback".

There shouldn't be anything special about copying out a subset of the src
rb to a temp before texturing from it, so just do it when we're figuring
out our src texture binding.
This drops Anuj's change to copy an extra border of 1 pixel around the src
area. I can't see how that change could be valid, and presumably if
there's some filtering problem at edges we just need to set the right
wrap mode.
v2: Don't fall back to swrast on non-2D/RECT/2D_MS textures when we can
still CopyTexSubImage. Fixes a segfault regression on i965 with

I think we can assert that renderbuffer size is <= maximum 2D texture
size. Our source coordinates should have already been clipped to the src
renderbuffer size, but haven't actually (so we could potentially have
trouble if there's scaling, and we're in the CopyTexImage path that tries
to use src size). However, this texture size dependency was blocking the
next refactors, so I'm not sure if we want to go ahead with this series
before we get the clipping sorted out or not.

We originally thought that GL 3.0 required GL_DEPTH_COMPONENT16 to map
exactly to Z16. However, we misread the specification, thanks in part
to LaTeX reordering the tables in the PDF.
Page 180 of the GL 3.0 specification (glspec30.20080923.pdf) says:
"[...] memory allocation per texture component is assigned by the GL to
match the allocations listed in tables 3.16-3.18 as closely as possible.
[...]
Required Texture Formats
[...]
In addition, implementations are required to support the following sized
internal formats. Requesting one of these internal formats for any
texture type will allocate exactly the internal component sizes and
types shown for that format in tables 3.16-3.17:"
Notably, however, GL_DEPTH_COMPONENT16 does /not/ appear in table 3.16
or table 3.17. It appears in table 3.18, where the "exact" rule doesn't
apply, and it falls back to the "closely as possible" rule.
The confusing part is that the ordering of the tables in the PDF is:
Table 3.16 (pages 182-184)
Table 3.18 (bottom of page 184 to top of 185)
Table 3.17 (page 185)
Presumably, people saw table 3.16, then saw the table immediately
following with DEPTH_COMPONENT* formats, and assumed it was 3.17.
Based on a patch by Chia-I Wu, but without the driconf option to force
Z16 to be used. It's not required, and there's apparently no benefit
to actually using it.

We've learned a few things since we originally disabled Z16; this attempts
to summarize the issue. I am no expert on this subject, though, so the
comment may not be totally accurate.
I did some benchmarking on GM45 and Ironlake, and discovered that for
GLBenchmark 2.7 EgyptHD, using Z16 was 3% slower on GM45 (n=15), and
4.5% slower on Ironlake (n=95). So, we can drop the "on Ivybridge"
aspect of the comment - it's always slower.
