It looks the original indirect mask was probably copied from
ANV.
Sascha Willems demo results:
tessellation ~4000 -> ~4200 fps
V2: continue lowering local indirects due to llvm deficiencies.

Here we make use of NIR the linking helpers to remove unused
varyings.

So it appears the Vulkan SPIR-V fma opcode can be equivalent to a
mad operation, and the fma hw opcode on AMD hw is issued like a double
opcode so is slower. Also the radeonsi stack does this.
This appears to improve performance on a number of games from Feral,
and thanks to Feral for noticing the problem.
I'm reposting this one as Marek indicated he thinks this is what
we should be doing on AMD hw.

This looks a bit ugly to me, but the existing codepath
is not terribly elegant as well.

With the shaders in the ssao demo, the nir_opt_if wasn't
working properly without this, after this the if gets optimised
so that loop unrolling gets called.
(loop unrolling fails due to instruction count, but at least
it gets to do that.)

This will allow to dump the active shaders when a hang is
detected. Only the ASM will be dumped for now.

Reduce size of radv_pipeline.c and improve code isolation. More
code can probably moved but it's a start.
