For Gen11 and prior, the dispatch mode for TCS was SINGLE_PATCH, and
this debug setting could be used to change it to 8_PATCH (falling back
to SINGLE_PATCH when shader couldn't be in the multi dispatch mode).
However after talking to Ken, seems this debug setting is not really
worth keeping around, so removing it.
For Gen12+ the only option is 8_PATCH, so it was always using that
dispatch mode as before.

Useful for hang debugging. Previously Anv incorrectly used DEBUG_SYNC
for this.

When CCS compression first came out on Skylake, we referred to it as
"renderbuffer compression", or RBC for short. However, that name has
long since fallen out of favor, and we refer to it as CCS nearly
everywhere.
This patch renames DEBUG_NO_RBC to DEBUG_NO_CCS inside the codebase
for clarity, and adds INTEL_DEBUG=noccs. The legacy INTEL_DEBUG=norbc
name continues to work, because it's one line of code and having both
names makes our lives easier in the interim.

INTEL_DEBUG is defined (since 4015e1876a) as:
#define INTEL_DEBUG __builtin_expect(intel_debug, 0)
which unfortunately chops off upper 32 bits from intel_debug
on platforms where sizeof(long) != sizeof(uint64_t) because
__builtin_expect is defined only for the long type.
Fix this by changing the definition of INTEL_DEBUG to be function-like
macro with "flags" argument. New definition returns 0 or 1 when
any of the flags match.
Most of the changes in this commit were generated using:
for c in `git grep INTEL_DEBUG | grep "&" | grep -v i915 | awk -F: '{print $1}' | sort | uniq`; do
perl -pi -e "s/INTEL_DEBUG & ([A-Z0-9a-z_]+)/INTEL_DBG(\1)/" $c
perl -pi -e "s/INTEL_DEBUG & (\([A-Z0-9_ |]+\))/INTEL_DBG\1/" $c
done
but it didn't handle all cases and required minor cleanups (like removal
of round brackets which were not needed anymore).
