i965/fs: Fix some untriggered optimization bugs with uncompressed/sechalf.

Browse source 
We have this support for firsthalf/sechalf instructions, which would be
called in the !has_compr4 (aka original gen4) 16-wide case.  We currently
only support 16-wide for gen5+, so we weren't tripping over this, but it
would have been a problem if we ever try to enable it.
