<pre>The `inline` keyword placed on the declarations on `__push_back_slow_path` and
`__emplace_back_slow_path` is needed to prevent them from appearing in
libc++.so's dynamic symbol table (for instantiations used inside the library).
However, they are marked also given hidden visibility, which should prevent
this in the first place.
Adding `inline` is problematic for two reasons:
1) It's not a real fix.
2) It can needlessly increase the binary size of users (because clang actually
uses `inline` as an inlining hint).
The second problem cause chrome to have a 1% binary size increase.
We should investigate why Clang is not hiding this symbol. We should also
seriously consider moving to explicit export lists.
@Louis, any thoughts?</pre>
