This is a fixup for the unit tests from r298278 (originally r298165). Since the buffer that RawB2 pointed at was later deleted, a new call to getBuffer may very well return a buffer at the same/old address. Which is fine. Just delete the spurious check. A Windows bot was occasionally hitting this in practice: http://lab.llvm.org:8011/builders/llvm-clang-lld-x86_64-scei-ps4-windows10pro-fast/builds/7086 llvm-svn: 298414
