  Changed paths:
    M clang/lib/AST/TypePrinter.cpp
    A clang/test/CodeGen/Inputs/debug-info-slash.cpp
    A clang/test/CodeGen/Inputs/debug-info-slash.h
    A clang/test/CodeGen/debug-info-slash.test

  Log Message:
  -----------
  Use windows baskslash on anonymous tag locations if using MSVCFormatting and it's not absolute path.

This fixes a nondeterminism on debug info when building on windows natively vs
cross building to windows.
