Restructure the COFF metadata handling to use the linker section grouping to emit section start/stop markers in the appropriate location. This allows us to lookup the sections statically without having to the walk the entire image structure. Introduce a constructor for PE/COFF binaries. This will ensure that the registration occurs for all modules appropriately. This should resolve rdar://problem/19045112. The registration should occur prior to `DllMain` being invoked from `DllMainCRTStartup`.
