  AMDGPU: Don't use branches to entry block in test

This created a weird loop making the tested registers live out of the
block, which I don't think is relevant to the purpose of the
tests. This caused regressions when the validity queries are changed
to use tests based whether the use instruction was a kill. If the
register was live out for the loop, it was still live.

I guess we could still do this in a narrow case where the value loops
back, but that's most a pointlessly complex case to handle.
