Reapply r278457 with test fixed to not abouse fs case sensitivity.
When the VFS uses a YAML file, the real file path for a
virtual file is described in the "external-contents" field. Example:
...
{
'type': 'file',
'name': 'a.h',
'external-contents': '/a/b/c/a.h'
}
Currently, when parsing umbrella directories, we use
vfs::recursive_directory_iterator to gather the header files to generate the
equivalent modules for. If the external contents for a header does not exist,
we currently are unable to build a module, since the VFS
vfs::recursive_directory_iterator will fail when it finds an entry without a
reliable real path.
Since the YAML file could be prepared ahead of time and shared among
different compiler invocations, an entry might not yet have a reliable
path in 'external-contents', breaking the iteration.
Give the VFS the capability to skip such entries whenever
'ignore-non-existent-contents' property is set in the YAML file.
