OK, should be fixed now. |

Is there a downside to just always passing |

This PR will enable RUSTC to generate PDB debuginfo files when targeting the MSVC toolchain. Mind that these are not full featured PDB files -- they just contain line tables, so you can get proper backtraces and step through your code, but variable values can't be inspected. We are just levering (LLVM's current support)[http://clang.llvm.org/docs/MSVCCompatibility.html] for creating Windows debuginfo. When LLVM's support gets better, we should benefit from that too without much effort. I also wanted to include some kind of auto test with this PR but I could not get the `rmake` tests to work properly when targeting MSVC. EDIT: Closes #19533
