i965: Fix max_wm_threads for CHV

Change max_wm_threads to match the spec on CHV. The max number of
threads in 3DSTATE_PS is always programmed to 64 and the hardware
internally scales that depending on the GT SKU. So this doesn't
change the max number of threads actually used, but it does affect
the scratch space calculation.

On CHV the old value was too small, so the amount of scratch space
allocated wasn't sufficient to satisfy the actual max number of

st/nine: Correctly handle when ff vs should have no texture coord input/output

Previous code semantic was:

. if ff ps will not run a ff stage, then do not output texture coords for this stage
for vs
. if XYZRHW is used (position_t), use only the mode where input coordinates are copied
to the outputs.

Problem is when apps don't give texture inputs. When apps precise PASSTHRU, it means
copy texture coord input to texture coord output if there is such input. The case
where there is no texture coord input wasn't handled correctly.

Drivers like r300 dislike when vs has inputs that are not fed.

Moreover if the app uses ff vs with a programmable ps, we shouldn't look at
what are the parameters of the ff ps to decide to output or not texture
coordinates.

The new code semantic is:

. if XYZRHW is used, restrict to PASSTHRU
. if PASSTHRU is used and no texture input is declared, then do not output
texture coords for this stage

The case where ff ps needs a texture coord input and ff vs doesn't output
it is not handled, and should probably be a runtime error.

This fixes 3Dmark05, which uses ff vs with programmable ps.

brw_fs_nir has only seen scalar bools so far, thanks to vector splitting,
and the ralloc of in glsl_to_nir.cpp will *usually* get you a 0-filled

i965: Add QWORD sizes to type_sz macro

GEN8 added the QWORD as a valid type for certain operations on the EU.
In order to calculate the number of registers used one must have the type
size as part of the equation. Quoting the formula in the code:

   regs_written = (dst.width * dst.stride * type_sz(dst.type) + 31) / 32;

Adding this separately for bisection since there is no simple way to add
an assert in the type_sz function.

NOTE: As a side note, I was confused for a while because it's impossible
to calculate the region, ie. registers needed, without vstride.  However,
at this point these are all part of the IR, and so no vstride must exist.
