Fixes dEQP-VK.reconvergence.*nesting* tests.
There are cases when cmod is set to an instruction that cannot have
conditional modifier. E.g. following:
find_live_channel(32) vgrf166:UD, NoMask
cmp.z.f0.0(32) null:D, vgrf166+0.0<0>:D, 0d
is optimized to:
find_live_channel.z.f0.0(32) vgrf166:UD, NoMask
v2:
- Add unit test to check cmod is not set to 'find_live_channel' (Matt Turner)
- Update flag_subreg when conditonal_mod is updated (Ian Romanick)
