a1f9ad2a - [SPARC] Fix-forward #154950 by returning true if SP::V8BAR is handled (#162424)

[SPARC] Fix-forward #154950 by returning true if SP::V8BAR is handled (#162424) Use-after-poison happens because after SP::V8BAR is handled, it erases MI, which therefore should not be inspected by `ExpandPostRA::run()`. This fixes a buildbot-reported issue from #154950 (https://lab.llvm.org/buildbot/#/builders/24/builds/13433).
