[clangd] Add a test URI scheme for lit tests to unbreak platform-specific URI failures.

[ioeric]

Summary

This should also fix the current windows buildbot breakage
(http://lab.llvm.org:8011/builders/clang-x86-windows-msvc2015/builds/9838/steps/ninja%20check%201/logs/stdio)

[sammccall]

Thanks for fixing this once and for all!

clangd/ClangdLSPServer.cpp

23

nit: URi -> URI

28

nit: just inline this at the registry site? we shouldn't be using it elsewhere

47

on windows you're passing C:\clangd-test and /foo.cpp here.
I think you should probably call native on the body before passing it here (and no need to do it after)

clangd/Protocol.cpp

36

I'd suggest not mentioning 'test' in the log message, and just making this a comment.
If someone passes e.g. http://, mentioning test probably adds more confusion than it resolves.
