A simple post-RA optimization which takes advantage of the
s_cbranch_vccz and s_cbranch_vccnz instructions.
It works on the following pattern:
vcc = v_cmp ...
scc = s_and vcc, exec
p_cbranch scc
The result looks like this:
vcc = v_cmp ...
p_cbranch vcc

For fragment shaders that only contain a discard, the exec mask has
to be zero'd and everything discarded.
It seems unnecessary to emit an export here because if the FS has no
exports, the compiler already emits a null export at the end.
