[libcxx] r249738 - Split <ctype.h> out of <cctype>.

[Adrian Prantl via cfe-commits]

To make it easier to find and investigate issues like this, I set up an experimental bot on the Green Dragon Jenkins installation on lab.llvm.org that builds a stage2 on Darwin with LLVM_ENABLE_MODULES:

I’ve configured it to dump the output of the CMake error log to facilitate diagnosis:
