[LLD] [MinGW] Implement the --no-seh flag Previously this flag was just ignored. If set, set the IMAGE_DLL_CHARACTERISTICS_NO_SEH bit, regardless of the normal safeSEH machinery. In mingw configurations, the safeSEH bit might not be set in e.g. object files built from handwritten assembly, making it impossible to use the normal safeseh flag. As mingw setups don't generally use SEH on 32 bit x86 at all, it should be fine to set that flag bit though - hook up the existing GNU ld flag for controlling that.
