[PATCH] D45442: Parse .h files as objective-c++ if we don't have a compile command.

[Sam McCall via Phabricator via cfe-commits]

sammccall added a comment.

Added a unit test, and cleaned up a couple of things to make it pass:

- GlobalCompilationDatabase.h wasn't self-contained due to incomplete types
- testPath() isn't very usable with subdirectories on windows



================
Comment at: clangd/GlobalCompilationDatabase.cpp:24
+  // Parsing as Objective C++ is friendly to more cases.
+  if (llvm::sys::path::extension(File) == ".h")
+    Argv.push_back("-xobjective-c++-header");

Yeah .C/.H is rare these days I think. (But present in Driver/Types.cpp)
