We were doing it ad-hoc before, as instructions with potential
aliasing problems were identified. But thanks to swizzling basically
anything can have aliasing, so just do it generally at source reg
setup time. This is somewhat inefficient, because sometimes an
operation doesn't need unaliasing protection if the swizzling is safe,
but the unaliasing before didn't cover those cases either.
Fixes piglit glsl-fs-loop.
We were patching up all the break and continues between the start of
our loop and the end of our loop, even if they were breaks/continues
for an inner loop. Avoiding patching already patched breaks/continues
fixes piglit glsl-vs-loop-nested.
one variable is a bitfield where the rest is never written to, which caused
valgrind to complain. Might have caused cso to not recognize an already stored
state. Reported by Christoph Bumiller.
The LOD is computed from texcoord partial derivatives and used to
select a mipmap level. Still some bugs in texel fetching. Lots of
rough edges and unfinished parts but the basics are in place.
Lots of changes to the lp_bld_arit.c code to support non-vector/scalar
datatypes.
While this c99 feature should work with most compilers, valgrind doesn't
really like it, and this only really saves some memory, we don't do this
in similar occasions (like the blend state) neither.

gallium: remove p_screen::surface_buffer_create
This isn't very useful without texture_blanket(), which has also been
removed.
Note that this function hasn't been removed from the old pipe_winsys
(u_simple_screen) still used internally by some drivers (eg softpipe).

gallium: remove texture blanket call
No longer needed, except for nouveau and egl/xll/native_ximage.c.
Fix for nouveau is to keep the call, but move it to an internal
function within nouveau.
Fix for that egl/x11 relies on gallium-sw-api branch or its successor.

drm_api: wrap comment
Change the texture data_ptr from just a single image pointer to an
array of image pointers, indexed by mipmap level.
We'll use this for mipmap filtering.
For now, the mipmap level is hard-coded to zero.
