Based on post-commit review discussion on2bd8493847with Richard Smith. Other uses of forcing HasEmptyPlaceHolder to false seem OK to me - they're all around pointer/reference types where the pointer/reference token will appear at the rightmost side of the left side of the type name, so they make nested types (eg: the "int" in "int *") behave as though there is a non-empty placeholder (because the "*" is essentially the placeholder as far as the "int" is concerned). This was originally committed in277623f4d5Reverted inf9ad1d1c77due to breakages outside of clang - lldb seems to have some strange/strong dependence on "char [N]" versus "char[N]" when printing strings (not due to that name appearing in DWARF, but probably due to using clang to stringify type names) that'll need to be addressed, plus a few other odds and ends in other subprojects (clang-tools-extra, compiler-rt, etc).
