  [TwoAddressInstruction] Handle physical registers with LiveIntervals (#66784)

Teach the LiveIntervals path in isPlainlyKilled to handle physical
registers, to get equivalent functionality with the LiveVariables path.

Test this by adding -early-live-intervals RUN lines to a handful of
tests that would fail without this.
