i965: Remove the BRW_NEW_INPUT_DIMENSIONS flag.

When I removed the proj_attrib_mask optimization, I also removed the
last consumer of this bit without realizing it.

Since nobody uses it, there's no point in flagging it.

intel: Require kernel 2.6.39 for relaxed relocation support.

Chris Wilson's relaxed relocation patch landed in March 2011.  Anyone
running pre-3.0 kernels probably isn't going to get the latest Mesa

intel: Remove check for kernel 2.6.29.

Now that we require 2.6.39, there's no need to also check for 2.6.29.
Calling drm_intel_bufmgr_gem_enable_fenced_relocs() without checking
should be safe, as it simply sets a flag.

This does remove the check for zero fences available, but that doesn't
seem worth checking.

intel: Do temporary CPU maps of textures that are too big to GTT map.

This still fails, since 8192*4bpp == 32768, which is too big to use the
blitter on.

intel: Avoid making tiled miptrees we won't be able to blit.

Doing so was breaking miptree mapping, which we really need to be able to
handle.  With this change, intel_miptree_map_direct() falls through to
doing a CPU mapping on the buffer like we need.

With the previous 2 patches, all of these should be fixed:
piglit max-texture-size (all 3 patches required!)

glsl: Refactor handling of ast_array_index to a separate function

extracting this code will make that a bit easier.

glsl: Remove some unnecessary uses of error_emitted

The error_emitted flag is used in semantic checking to prevent spurious
cascading errors.  For example,

void foo(sampler2D s, float a)
{
    float x = a + (1.2 + s);

    ...
}

should only generate a single error.  Without the error_emitted flag for
the first error, "a + ..." would also generate an error.

However, a bunch of cases in _mesa_ast_array_index_to_hir that were
setting error_emitted would mask legitimate errors.  For example,

    vec4 a[7];
    float b = a[3.14];

should generate two error (float index and type mismatch in assignment).
The uses of error_emitted would cause only the first to be emitted.

This patch removes most of the places in _mesa_ast_array_index_to_hir
that would set the error_emitted flag.

glsl: Don't emit spurious errors for constant indexes of the wrong type

Previously the shader

would have generated the errors

0:2(33): error: array index must be integer type
0:2(36): error: array index must be < 6

Now only

0:2(33): error: array index must be integer type

will be generated.

glsl: Don't early-out for error-type inputs

Check the type of the array operand and the index operand before doing
other checks.  This simplifies the code a bit now (eliminating the
error_emitted parameter), and enables some later functional changes.

The shader

uniform float x[6];
uniform sampler2D s;
void main() { gl_Position.x = xx[s + 1]; }

still generates (only) the two expected errors:

0:3(33): error: `xx' undeclared
0:3(39): error: Operands to arithmetic operators must be numeric
