Radeon generic scissors code had problem that some of code was using exclusive
and some inclusive bottom right corner. Only r600 driver is using exclusive
coordinate so changed generic code to pass inclusive coordinate and r600 driver
changes BR coordinate to be exclusive.
- max texture size is 8k, but mesa doesn't support
that at the moment.
- attempt to set shader limits to what the hw actually
supports
- clean up some old r300 cruft
- no need to explicitly disable irqs. This is fixed
in the drm now.

- MUL_LIT is ALU.Trans instruction
- some Trans instructions can take 3 arguments
- don't clobber dst.x, use dst.z as temp, it'll get written correct
value in last insn
- respect source swizzles
1D tile span support for depth/stencil/color/textures
Z and stencil buffers are always tiled, so this fixes
sw access to Z and stencil buffers. color and textures
are currently linear, but this adds span support when we
implement 1D tiling.
This fixes the text in progs/demos/engine and progs/tests/z*
Mostly fixes progs/demos/lodbias when MESA_TEX_PROG=1. But the LOD still
seems off by -1 or so.
May be an issue with the params passed to _swrast_compute_lambda()
In get_array_bounds we were previously defining a user buffer sized as
(nr_vertices * stride). The trouble is that if the vertex data
occupies less than stride bytes, the extra tailing (stride - size)
bytes may extend outside the memory actually allocated by the app and
caused a segfault.
To fix this, define a the buffer bounds to be:
ptr .. ptr + (nr-1)*stride + element_size
The warnings introduced in 1f309c40b8
would pour out generously from some applications. This patch adds a
"warn once" wrapper macro, heavily inspired by
src/mesa/drivers/dri/r600/radeon_debug.h

If the 'end' index is out of bounds issue a warning as before. But instead
of just no-op'ing the draw call, examine the actual array indices to see
if they're OK. If the max array index is out of bounds, issue another
warning and no-op the draw call. Otherwise, draw normally. This is a
debug build-only feature since it could impact performance.
This "fixes" the missing torus in the OGL Distilled / Picking demo.
This happens to rendering with textures with a border, which had resulted
in a segfault on dereferencing the irb.
