Crash on Windows in Preprocessor

[aeubanks]

On Windows/VSCode, clangd built at revision 0e8506debae3

I'm running clangd over the LLVM codebase. Not sure which file is causing this. If you'd like an actual repro, I can try to dig more into coming up with a repro, but hopefully there's something obvious from the stack trace.

Assertion failed: isValid(), file ../../clang/include/clang/Basic/SourceLocation.h, line 327
