Don't really know what they are yet but for groups of textures, the
last one should use mode "p" and the others "t".

Put them before first uses instead of right after the texturing
instruction and cull unnecessary barriers.

We have to actually emit RET, too, of course, not just the PRERET.

The idea is not to use pb_map and pb_unmap wrappers, calling straight
into the winsys.

As noted in commit be4e46b21a60cfdc826bf89d1078df54966115b1,
this was missing before.
NOTE: This is a candidate for the 8.0 branch.

A little analysis shows that the worst-case value for "nr" is 17:
- base_mrf = 2 ... 2
- header present (say gen == 5) ... 4
- aa_dest_stencil_reg (stencil test) ... 5
- SIMD16 mode: += 4 * reg_width ... 13
- source_depth_to_render_target ... 15
- dest_depth_reg ... 17
This resulted in us setting base_mrf to 2 and mlen to 15. In other
words, we'd try to use m2..m16. But m16 doesn't exist pre-Gen6. Also,
the instruction scheduler data structures use arrays of size 16, so this
would cause us to access them out of bounds.
While the debugger system routine may need m0 and m1, we don't use it
today, so the simplest solution is just to move base_mrf back to 1.
That way, our worst case message fits in m1..m15, which is legal.
An alternative would be to fail on SIMD16 in this case, but that seems
a bit unfortunate if there's no real need to reserve m0 and m1.
Fixes new piglit test shaders/depth-test-and-write on Ironlake.

To ensure that the alloca is at the top of the function body, otherwise
LLVM will not eliminate them, causing stack misalignment on 32bits.

This is taken from the ogl-math project, with Inverse renamed to adj
(since it's not actually the inverse), transposed, and our types
plugged in. There are potential CSE opportunities in this code
(particularly for hardware with RCP but not DIV), but we should be
doing CSE anyway, so don't hand-optimize.

This takes advantage of the builtin compiler to generate IR into a
string, the same way we read GLSL for function prototypes for our
profiles.

It appears that when using 'ld' with the offset bits, address bounds
checking happens before the offset is applied, so parts of the drawing
in piglit texelFetchOffset() with a negative texcoord go black.
