r600g: fix LIT to handle src==dst properly

Current LIT implementation uses dst components for storing temp
results, possibly overwriting still needed values (depends on the
swizzles).
This patch uses temp reg for one of such cases (found in etqw) and
fixes "LIT R.z, R.xyzz".

Tested on evergreen. Fixes some etqw-demo rendering glitches when
"Lighting" is set to "High" in the settings.
