c++: Use mapped reads and writes when munmap and msync are available
Module support is broken when MAPPED_READING and MAPPED_WRITING
are defined to 0. This causes internal compiler errors in the
permissive-error-1.C and permissive-error-2.C tests.
HP-UX 11.11 doesn't define _POSIX_MAPPED_FILES but it does have
munmap and msync. Testing indicates support is sufficient for
c++ modules, so use checks for these functions instead of
_POSIX_MAPPED_FILES check.
