[llvm] r220667 - Revert "Include stddef.h before including cxxabi.h" to un-break buildbot

[Rui Ueyama]

The error was
http://lab.llvm.org:8011/builders/llvm-clang-lld-x86_64-debian-fast/builds/19211.
I already fixed that and re-committed. The cause of the issue is that C++
code given to check_cxx_source_compile didn't have main function.
