Esme-Yi 2eb7e5f0ed [yaml2obj] Do not write the string table if there is no string entry. 
Summary: yaml2obj shouldn't create the string table that isn't needed
         - doing so wastes time and disk space.

Esme-Yi ec43c1213a [NFC][XCOFF] Replace structs FileHeader32/SectionHeader32 with constants. 
Summary: Some structs like FileHeader32/SectionHeader32
defined in llvm/include/llvm/BinaryFormat/XCOFF.h seem
unnecessary, because we only need their size. So this
patch removes them and defines size constants directly.
