AMDGPU: Fix LCSSA phi lowering in SILowerI1Copies
Summary:
When an LCSSA phi survives through instruction selection, the pass
ends up removing that phi entirely because it is dominated by the
logic that does the lanemask merging.
This then used to trigger an assertion when processing a dependent
phi instruction.
