i965: Replace references to stencil region size with buffer size
It is unwise to use a stencil region's size to determine its
renderbuffer's size, because at region creation we fudge the width and
height to accomodate interleaved rows. (See the comment for MESA_FORMAT_S8
in intel_miptree_create()). Most users of stencil_region->{width,height}
should be converted to use stencil_rb->{Width,Height}.
We have already done the replacement in several locations. This patch
continues the replacement in {brw,gen7}_emit_depthbuffer(). To make those
functions look consistent, I've also done the equivalent replacement for
the depth buffer.

glsl: fix glsl optimization infinite loop from copy_propagation_elements
The trick was to produce an assignment in the IR along the lines of:
(assign (xyzw) (var_ref R0) (swiz wwww (var_ref R0) ))
which occurs only rarely even in code that looks like it should do
this, because of the assignment temporaries generated in ast_to_hir.
From the IR above, this optimization pass would then propagate
references of R0 into R0.wwww (seems reasonable), but without this
patch, a later reference of R0.wwww would see R0 first, turning that
into R0.wwww.wwww, which triggered opt_swizzle_swizzle, and then we
looped back to this code to do it again. Avoid that by skipping over
the usual ir_rvalue visitor's ir_swizzle hook, so that we get
handle_rvalue() on the ir_swizzle itself, not its referenced value.
Looking at only the swizzle will always optimize away at least as much
as looking at the swizzle's refererenced value.
We now still claim to propagate r0.w into r0.w, but at least we don't
trigger the loop.

i965/fs: Fix projector==1.0 optimization pre-gen6.
The optimization was supposed to turn an attribute component that was
always 1.0 into a mov of 1.0. But by leaving loop this patch removes
out of that test, we applied the projection correction to the 1.0 and
got some other value, breaking openarena once it was converted to
using the new compiler backend.
Originally this hunk was separate from the former loop to make the
generated instructions slightly better pipelined. We now have
automatic instruction scheduling to handle that, and the generated
instruction sequence looked the same to me after this change (except
for the bugfix).
