Tom Stellard 89d0e99f86 R600/SI: Fix verifier errors from the SIAnnotateControlFlow pass ...

This pass was generating 'Instruction does not dominate all uses!'
errors for programs which had loops with a condition variable that
depended on the result of a phi instruction from outside of the loop.

The pass was inserting new phi nodes outside of the loop which used values
defined inside the loop.
