Non-volatile gl_HelperInvocation after demote is undefined.
In order to avoid application bugs, make it volatile if we use demote.

It doesn't make sense to have two sets of opcodes for this when all backends
that support the flush_to_zero variant just rely on the global floating point
mode anyway.

Dumps the value associated with each SPIR-V ID after parsing the module.
This will show the intermediate vtn_* values that spirv_to_nir uses.
Only a subset of detailed information is printed at the moment (focus on
pointers and pointer types), but it is easy to add for other value types
later.
Example output when running crucible with the debug option enabled.

AGX has limited border colour hardware. To support full
customBorderColorWithoutFormat semantics, we're forced to emulate in shaders at
a substantial performance penalty. Actually, that's needed just to pass CTS
because of other hardware issues stacking on top of each others... Hooray!
Add the texops we need to facilitate efficient custom border colour lowering.

Also, re-organize a bit to match the spec better. There are now
capabilities which need to be set to constant true which we didn't have
to se in the old caps struct and this makes it all more obvious.

With TES, the primitive ID is an input variable but it's considered a
sysval by SPIRV->NIR. Though, its value is greater than
VARYING_SLOT_VAR0 which means its location was adjusted by mistake.
