fixes a C++03 only failure

[cjdb]

fixes inclusion issues that weren't being replicated locally

The libc++abi test diff is literally + #include <algorithm>\n, but Arcanist said the following and forced it to be treated as a binary:

Diff for 'libcxxabi/test/test_demangle.pass.cpp' with context is
5,403,317 bytes in length. Generally, source changes should not be this
large. If the file is not a text file, you can mark it 'binary'. Mark
this file as 'binary' and continue?

[ldionne]

LGTM but I'd like to understand the modulemap changes.

libcxx/include/module.modulemap

235

Why do those export unwrap_iter?

[cjdb]

libcxx/include/module.modulemap

235

Something to do with Clang modules not exporting them properly, which leads to linker errors regarding __rewrap_iter. I don't have a good answer.
