nir: add conditional discard optimisation (v4)
This is ported from GLSL and converts
if (cond)
discard;
into
discard_if(cond);
This removes a block, but also is needed by radv
to workaround a bug in the LLVM backend.
v2: handle if (a) discard_if(b) (nha)
cleanup and drop pointless loop (Matt)
make sure there are no dependent phis (Eric)
v3: make sure only one instruction in the then block.
v4: remove sneaky tabs, add cursor init (Eric)
