[libc++] Always generate a __config_site header Before this patch, the __config_site header was only generated when at least one __config_site macro needed to be defined. This lead to two different code paths in how libc++ is configured, depending on whether a __config_site header was generated or not. After this patch, the __config_site is always generated, but it can be empty in case there are no macros to define in it. More context on why this change is important -------------------------------------------- In addition to being confusing, this double-code-path situation lead to broken code being checked in undetected in 2405bd689815, which introduced the LIBCXX_HAS_MERGED_TYPEINFO_NAMES_DEFAULT CMake setting. Specifically, the _LIBCPP_HAS_MERGED_TYPEINFO_NAMES_DEFAULT <__config_site> macro was supposed NOT to be defined unless LIBCXX_HAS_MERGED_TYPEINFO_NAMES_DEFAULT was specified explicitly on the CMake command line. Instead, what happened is that it was defined to 0 if it wasn't specified explicitly and a <__config_site> header was generated. And defining that macro to 0 had the important effect of using the non-unique RTTI comparison implementation, which changes the ABI. This change in behavior wasn't noticed because the <__config_site> header is not generated by default. However, the Apple configuration does cause a <__config_site> header to be generated, which lead to the wrong RTTI implementation being used, and to https://llvm.org/PR45549. We came close to an ABI break in the dylib, but were saved due to a downstream-only change that overrode the decision of the <__config_site> for the purpose of RTTI comparisons in libc++abi. This is an incredible luck that we should not rely on ever again. While the problem itself was fixed with 2464d8135e2a by setting LIBCXX_HAS_MERGED_TYPEINFO_NAMES_DEFAULT explicitly in the Apple CMake cache and then in d0fcdcd28f95 by making the setting less brittle, the point still is that we should have had a single code path from the beginning. Unlike most normal libraries, the macros that configure libc++ are really complex, there's a lot of them and they control important properties of the C++ runtime. There must be a single code path for that, and it must be simple and robust. Differential Revision: https://reviews.llvm.org/D80927
