Rui Ueyama 14876abb3d [PECOFF] Set the correct PE header field value. 
The charcateristics field should not have IMAGE_FILE_32BIT_MACHINE bit but have
IMAGE_FILE_LARGE_ADDRESS_AWARE bit for PE32+.

Rui Ueyama ebc13c47f2 [PECOFF] Do not emit a section if it's empty. 
The PE32+ loader does not seem to like an executable with an empty section, so
we should not emit a section if it's empty.

Rui Ueyama 7d1bf45047 [PECOFF] Fix PE/COFF optional header size for PE32+. 
The optional header for PE32+ is a bit larger than PE32 because some of
its fields are extended to 8 bytes.
