Include Support/FileUtilities.h.

Print module identifier in DumpSymbolNamesFromModule().
In DumpSymbolNamesFromFile(), check whether it is an archive or a bytecode
 file, and call the corresponding reader function (ParseBytecodeFile or
 ReadArchiveFile).
Unconditionally set MultipleFiles for archives.
Fixes PR117.
