[Mesa-dev] [PATCH 1/3] i965/gen4-5: Set ENDIF dst and src0 fields to the null register.

The hardware docs don't mention explicitly what these fields should be, but I've verified experimentally on ILK that using a GRF as destination causes the register to be corrupted when the execution size of an ENDIF instruction is higher than 8 -- and because the destination we were using was g0, e
