Marek Olšák 8def3f865d agx,freedreno,intel,lima,panfrost,svga,virgl,zink: fix supports_indirect_inputs 
The GLSL compiler always lowers inputs to temps for VS and GS, so exclude
them from driver support because the GLSL compiler will no longer do that
unconditionally. Thus, indirect VS and GS inputs are completely untested
and broken in a lot of drivers.

Bifrost compiler

Register file

Defined partially in software, partially in hardware.

Blend shaders

R0 - R3: input (color #0) R4 - R7: input (color #1) R8 - R15: general purpose R48: return address

Fragment

Anything live during BLEND must respect blend shader registers.

R0 - R3: preloaded (message #0) R4 - R7: preloaded (message #1) R57 - R63: preloaded (various)

R0 - R15: general purpose (full threads) R48 - R63: general purpose (full threads)

R32 - R47: general purpose (half threads, or v6)
