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)

I am not really that much familiar with nir, so I apologize if what I write
below is wrong.
What if we had something like:
a = 0;
if (x) {
discard_if(y);
a = 1;
}
Then if (x && !y), we must not discard and both at the same time set a to
1. Your transformation would probably change it to:
