Heaven LDS usage for LS+HS is below. The masks are "outputs_written"
for LS and HS. Note that 32K is the maximum size.
Before:
heaven_x64: ls=1f1 tcs=1f1, lds=32K
heaven_x64: ls=31 tcs=31, lds=24K
heaven_x64: ls=71 tcs=71, lds=28K
After:
heaven_x64: ls=3f tcs=3f, lds=24K
heaven_x64: ls=7 tcs=7, lds=13K
heaven_x64: ls=f tcs=f, lds=17K
All other apps have a similar decrease in LDS usage, because
the "outputs_written" masks are similar. Also, most apps don't write
POSITION in these shader stages, so there is room for improvement.
(tight per-component input/output packing might help even more)
It's unknown whether this improves performance.

LS is merged into TCS. If there is no TCS, LS is merged into fixed-func
TCS. The problem is the fixed-func TCS was ignored by scratch update
functions, so LS didn't have the scratch buffer set up.
Note that Mesa 17.1 doesn't have merged shaders.

What we care about is whether PrimID is used while tessellation is
enabled; whether it's used in TCS/TES or further down the pipeline is
irrelevant.

OpenGL uses at most 32 generic outputs/inputs in any stage, and they always
have a shader IO index and therefore fit into the outputs_written/
inputs_read/kill_outputs fields.
However, Nine uses semantic indices more liberally. We support that
in VS-PS pipelines, except that the optimization of killing outputs
must be skipped.

In a VS->TCS->TES->PS pipeline, the primitive ID is read from TES exports,
so it is as if TES were using the primitive ID.
Specifically, this fixes a bug where the primitive ID is not reset at
the start of a new instance.
