Summary: MC-COFF: section.bss always has .size as 0
Product: libraries

It seems mccoff emits .bss with size 0 in section headers.
In getSectionFileSize(), *virtual* section is treated as size zero.
A trivial patch. Now I can build FileCheck.exe and tblgen.exe with clang++
-integrated-as. opt.exe, clang.exe &c still crash for me.
