[cfe-dev] Problem with building Clang and LLVM using Xcode

I tried what you said.  I could run clangd in Xcode, but as you
mentioned it's not possible to choose clang to run.  It seems that
Xcode doesn't see "clang-6.0" as an executable file.  It assumes that
".0" at the end of the filename is the extension, so it is a
non-executable file.  I removed ".0" from the name, then I could run
it.  I don't know if this will cause problems along the way.  I
haven't started to debug clang yet, but if I run into problems, I'll
report it here.  Thanks!
