Summary: https://reviews.llvm.org/D49240 led to symbol size problems in Chromium, and we expect this may be the case in other projects built in debug mode too. Instead, unless users explicitly ask for internal_linkage, we use always_inline like we used to. In the future, when we have a solution that allows us to drop always_inline without falling back on internal_linkage, we can replace always_inline by that. Note that this commit introduces a change in contract for existing libc++ users: by default, libc++ used to guarantee that TUs built with different versions of libc++ could be linked together. With the introduction of the _LIBCPP_HIDE_FROM_ABI_PER_TU macro, the default behavior is that TUs built with different libc++ versions are not guaranteed to link. This is a change in contract but not a change in behavior, since the current implementation still allows linking TUs built with different libc++ versions together.
