I put the BRW_NEW_*_PROG_DATA flags at the beginning so that
brw_state_cache.c can still continue using 1 << brw_cache_id.
I also added a comment explaining the difference between
BRW_NEW_*_PROG_DATA and BRW_NEW_*_PROGRAM, as it took me a long time
to remember it.
Non-mechanical changes:
- brw_state_cache.c and brw_ff_gs.c now signal .brw, not .cache.
- brw_state_upload.c - INTEL_DEBUG=state changes.
- brw_context.h - bit definition merging.
v2: Correct the explanation of BRW_NEW_*_PROG_DATA to mention
state-based recompiles, and nix the "proper subset" claim,
as it's false. (Caught by Kristian Høgsberg).

Now that we've moved a bunch of CACHE_NEW_* bits to BRW_NEW_*, the only
ones that are left are legitimately related to the program cache. Yet,
it seems a bit wasteful to have an entire bitfield for only 7 bits.
State upload is one of the hottest paths in the driver. For each atom
in the list, we call check_state() to see if it needs to be emitted.
Currently, this involves comparing three separate bitfields (mesa, brw,
and cache). Consolidating the brw and cache bitfields would save a
small amount of CPU overhead per atom. Broadwell, for example, has
57 state atoms, so this small savings can add up.
CACHE_NEW_*_PROG covers the brw_*_prog_data structures, as well as the
offset into the program cache BO (prog_offset). Since most uses refer
to brw_*_prog_data, I decided to use BRW_NEW_*_PROG_DATA as the name.
Removing "cache" completely is a bit painful, so I decided to do it in
several patches for easier review, and to separate mechanical changes
from manual ones. This one simply renames things, and was made via:
$ for file in *.[ch]; do
sed -i -e 's/CACHE_NEW_\([A-Z_\*]*\)_PROG/BRW_NEW_\1_PROG_DATA/g' \
-e 's/BRW_NEW_WM_PROG_DATA/BRW_NEW_FS_PROG_DATA/g' $file
done
Note that BRW_NEW_*_PROG_DATA is still in .cache, not .brw!
The next patch will remedy this flaw. It will also fix the
alphabetization issues.

This was added in September 2013 when we first implemented the fast
(but lower quality) derivatives. A quick Google search didn't turn
up anyone using or recommending the option, so I suspect no one does.
Applications that want to control the quality of their derivatives can
use the new GL_ARB_derivative_control extension, or use the glHint
mechanism. The driconf option seems superfluous.

We've got two mostly-independent operations in each QPU instruction, so
try to pack two operations together. This is fairly naive (doesn't track
read and write separately in instructions, doesn't convert ADD-based MOVs
into MUL-based movs, doesn't reorder across uniform loads), but does show
a decent improvement on shader-db-2.

glsl: implement switch flow control using a loop
The SB backend was falling over in an assert or crashing.
Tracked this down to the loops having no repeats, but requiring
a working break, initial code just called the loop handler for
all non-if statements, but this caused a regression in
tests/shaders/dead-code-break-interaction.shader_test.
So I had to add further code to detect if all the departure
nodes are empty and avoid generating an empty loop for that case.

- p_atomic_cmpxchg() was returning the new value on success, instead of
the old
