    M llvm/test/Transforms/SCCP/freeze.ll

  Log Message:
  -----------
  Reapply [SCCP] Constant propagation through freeze instruction

Reapply with extra check for struct types, which caused buildbot
failures last time.

-----

The freeze instruction has not been handled by SCCPInstVisitor.
This patch adds SCCPInstVisitor::visitFreezeInst(FreezeInst &I)
method to handle freeze instructions.
