It might be better to add an instruction to normalize the
coordinates for rectanglular textures as there are some limitations
to wrap modes on unnormalized tex coords.

R300 hardware (but _not_ R500) hardware requires an enabled texture unit
if KIL is used in fragment programs. We now work around the CS checker
correctly when enabling such a fake texture unit.

We used to not always correctly re-emit the Z buffer size in all cases,
in particular the clear path, and invalidated state was not always picked
up correctly.
This fixes a bug where the kernel CS checker correctly complains about
a Z buffer that is too small.
Note that this bug was probably only visible with ridiculously high
framerates, i.e. glxgears.

This almost fixes compressed mipmapped textures on r200, though some small
mip levels are still broken.
Leave r300 compressed texture stride as is though afaik it's different
to pre-radeon-rewrite too. Also do the fixup for rs600 uncompressed row stride
at same place.

The LOOP/ENDLOOP pair is renamed to BGNFOR/ENDFOR as its behaviour
is similar to a C language for-loop.
The BGNLOOP2/ENDLOOP2 pair is renamed to BGNLOOP/ENDLOOP as now
there is no name collision.
Casting an unsigned int to or from a pointer directly gives warnings on
x86-64. Add wrappers to silence the warnings.

The field is not used, and in any case it would be more interesting to
manipulate from *outside* the compiler if we ever wanted to load several
fragment programs at the same time or something.

When a texutre transfer is mapped for writing, mark the texture dirty
when unmapped. This was done in surface creation, and this commit moves
it to happen in texture unmapping.

For GL_RGB5, GL_RGB4 and GL_R3_G3_B2, prefer
PIPE_FORMAT_R5G6B5_UNORM over PIPE_FORMAT_A1R5G5B5_UNORM, since hardware
is more likely to support the previous format for rendering.

If a texture image is bound to a framebuffer for render-to-texture, but
the hardware doesn't support rendering to its internal format,
report the framebuffer as incomplete with FRAMEBUFFER_UNSUPPORTED.

The only valid usage for LOOP/ENDLOOP instructions
is LOOP[0] as a destination register.
The only valid usage for the remaining instructions
is LOOP[0].x as an indirect register.
