Summary: r323164 made lld-link not overwrite import libraries when their contents haven't changed. MSVC's link.exe does this only when performing incremental linking. This change makes lld-link's import library overwriting similarly dependent on whether or not incremental linking is being performed. This is controlled by the /incremental or /incremental:no options. In addition, /opt:icf, /opt:ref, and /order turn off /incremental and issue a warning if /incremental was specified on the command line.
