MSVC link.exe cannot handle associative sections that refer later sections in the section header. Technically, such COFF object doesn't violate the Microsoft COFF spec, as the spec doesn't say anything about that, but still we should avoid doing that to make it compatible with MS tools. This patch assigns smaller section numbers to non-associative sections and larger numbers to associative sections. This should resolve the compatibility issue.
