As mandated by the Standard's various synopses, e.g. [iterator.synopsis]. Searching the TeX source for '#include' is a good way to find all of these mandates. The new tests are all autogenerated by utils/generate_header_inclusion_tests.py. I was SHOCKED by how many mandates there are, and how many of them libc++ wasn't conforming with.
