intel/fs: Mark source 0 of bcsel as needing Boolean resolve

The other sources of the bcsel behave like the sources of an and or other logical operation. However, source zero behaves differently. It is evaluated as a Boolean, so it needs to be resolved.

No shader-db changes, but the tests mentioned in the bug get a couple instructions added back.
