DRI: Put back missing break-statement

The break in the __DRI_ATTRIB_RENDER_TYPE case was accidentally
removed in commit 5cf2c5851bcd29c2d53bb04ab692b4b156f5a74d.  This puts
it back.

Revert "mesa: Fix unsigned comparison."

This reverts commit f9504e75f02586a8561733e0e2711c65efa2979d.

This patch is incorrect.

glsl: Remove unsigned greater than or equal zero comparison.

mesa: Fix unsigned comparison.

glsl: Remove unsigned greater than or equal zero comparison.

glsl: Return NULL on _slan_gen_asm error path on non-debug builds.

Exit the function early on the error path, instead of continuing, to
prevent a null pointer dereference later on.

glsl: Add assert to check input to strcmp.

mesa: Add asserts to check inputs to memcpy.

r300: make blit code work on swtcl machines.

Only tested this on my rv530 with R300_NO_TCL=1, but it works there
at least. It would be nice to fix the tex_offset by chaning the vertex
program on tcl to read from offset 6 but this isn't really necessary.

i915: Use x,y drawing offsets instead of changing buffer offsets.

This should fix rendering into mipmaps of tiled textures.

i915: Tell the kernel when we actually need fence registers on our BOs.

This improves tiled texture performance of OA on my 945 from 25.3fps
to 29.0fps, whereas untiled is 28.2fps, by avoiding stalls for fence
register changes.

intel: Use drm_intel_bo_alloc_tiled for region allocs.

This moves the logic for how to align pitches, heights, and sizes of
objects to one central location.  Fixes rendering with texture tiling
on i915.  Note that current libdrm is required for the change for
I915_TILING_NONE pitch alignment.

i915: Don't do the pitch expansion for tiled buffers.

The weirdness that led to the bumping of pitch for those 512/1024
pixels is that in taking a 2x2 subspan or bilinear filtering we'd end
up hitting the same channel in 2 different pages, leading to lower
performance.  With tiling, that doesn't occur, so we don't need to
waste the memory.
