i965: Stop advertising GL_MESA_ycbcr_texture.

The "new" fragment shader backend has never supported the necessary
color conversion code for this to work.  We began using the new backend
in Mesa 7.10 for GLSL (commit a81d423d93f22a948f3aa4bf73, October 2010),
and for ARB_fragment_program in Mesa 9.1 (commit 97615b2d8c7c3cea6fd3a4,
August 2012).

I haven't heard any complaints, so I don't think anyone will miss this
feature.  I believe mplayer used it at one point, but these days
defaults to other paths anyway.

freedreno/a3xx/compiler: fix neg mov's

create_mov() was fixed up to handle neg/abs properly for interal mov's,
using absneg.f, but forgot to fix it for TGSI MOV's.  The problem with
using add.f to handle negated mov's is that we can only take a single
const reg src.  So:

  MOV TEMP[n], -CONST[m]

would turn into:

  add.f Rdst, (neg)CONST[m], 0.0

which would not work.  Anyways, just remove the extra code and always
use create_mov() which DTRT.

freedreno/a3xx: deal with optimized tex instructions

Keep track of whether we actually have any sam instructions in the
resulting shader, rather than using TGSI SAMP declarations.  If the sam
instruction is optimized out, because the result is not used, we don't
want to emit texture state, etc.  In fact emitting sampler state and/or

In theory this should never happen for a "normal" shader, unless the
