Fixes a regression from commit 660ed923de.
The basic idea is to look at the format of the dest renderbuffer and
choose either GLubyte or GLfloat for colors. The previous code used
_mesa_format_to_type_and_comps() which could return a bunch types other
than ubyte/float.
Determine the datatype at renderbuffer mapping time to avoid frequent
calls to the format query functions.

Fix build with llvm-3.1svn.
llvm-3.1svn r149918 changed BufferMemoryObject::getExtent and
BufferMemoryObject::readByte from const member functions to non-const
member functions in include/llvm/Support/MemoryObject.h.

Ironlake appears to check our pointer against the General State Base
Address upper bound, rather than ignoring the zero bound as it ought.
Unfortunately, since we leave GSBA set to zero, there is no logical
upper bound. Set it to the maximum possible value, which should work
since our virtual addresses only go up to 2GB.

Improves nexuiz performance 0.65% +/- .10% (n=5) on my gen6, and .39%
+/- .11% (n=10) on gen7. No statistically significant performance
difference on warsow (n=5, but only one shader has MADs).
v2: Add support for MADs in 16-wide by using compression control.
v3: Don't generate MADs when it will force an immediate to be moved to a temp.
(it's not clear whether this is a win or not, but it should result in less
questionable change to codegen compared to v2).

Our only instruction with a 3rd source so far was linterp, and that
value was never register-allocated.

WGL_ARB_pixel_format establishes the existence of pixel formats which
are invisible to GDI.
However we still need to pass a valid pixelformat to GDI, so that
context creation/binding works.
The actual WGL_TYPE_RGBA_FLOAT_ARB implementation is from Brian Paul.
The mapping from TEXTURE_x_INDEX to GL_TEXTURE_x was broken in
alloc_proxy_textures() because the elements in the targets[] array
were in the wrong order.
This didn't actually cause any failures since we never really use the
proxy texture's Target field. But let's get it right.
NOTE: This is a candidate for the 8.0 branch.
Use the float tables instead. Pixel maps are seldom used so this
shouldn't be a big deal. Next, we can get rid of the gl_pixelmap::Map8
array.

There's a mismatch in row strides for compressed textures between
what Driver.MapTextureImage() returns and what the software fetch-texel
functions use. Move it down a layer. The next step would be to fix
this in the fetch-texel functions.
Just use pow() instead. Spot lights aren't too common and fixed-function
lighting isn't as important as it used to me.
This saves 32KB per context. Each table was 4KB and there's 8 lights.
This is a shader based median filter, generally
used for noise reduction, it could still need some
improvements, but should usually work out of the box.

The wm max threads is in the same dword as the dispatch enable. The
hardware gets super angry if you set max threads to 0, even if you
aren't dispatching threads.
Avoid unrollong loops that are either nested loops or
where the loop body times the unroll count is huge.
The change is far from being perfect but it extends the
loop unrolling decision heuristic by some additional
safeguard. In particular this cuts down compilation of
a shader precomputing atmospheric scattering integral
tables containing two nesting levels in a loop from
something way beyond some minutes (I never waited for
it to finish) to some fractions of a second.
This fixes piglit tests glsl-fs-unroll-explosion and
glsl-vs-unroll-explosion on r600g.

width, height parameter in glTexImage2D() includes: texture image
width + 2 * border (if any). So when doing the texture size check
in _mesa_test_proxy_teximage() width and height should not exceed
maximum supported size for target texture type + 2 * border.
i.e. 1 << (ctx->Const.MaxTextureLevels - 1) + 2 * border
Texture border is anyway stripped out before it is given to intel
or gallium drivers.
