i965: Rename CACHE_NEW_*_PROG to BRW_NEW_*_PROG_DATA.

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.
