DebugInfo: don't require full definitions for friend classes Fixes a crash-on-valid introduced by r188486 (which should've occurred earlier but for a blatant bug where calling createFwdDecl from the requireCompleteType callback was useless under -flimit-debug-info and we were just getting lucky with other later callbacks requiring the type anyway). llvm-svn: 188622

DebugInfo: omit debug info for friends GCC ToT doesn't do this & it's worth about 3.2% on Clang's DWO file size with Clang. Some or all of this may be due to things like r190715 which could have source fixes/improvements, but it's not clear that's the case and that doesn't help other source bases. llvm-svn: 190716

// Emitting debug info for friends unnecessarily bloats debug info without any
// known benefit or debugger feature that requires it. Re-enable this is a
// use-case appears.
