gollvm: support -fPIE/-fno-PIE/-fpie/-fno-pie

Make sure that all of the various PIE compiler options are supported
properly. Prior to this point the driver accepted -fpic/-fPIC and
-pie/-no-pie but not -fPIE/-fno-PIE/-fpie/-fno-pie. As with clang,
rightmost pic/pie flag wins, e.g. -fpic -fno-PIE turns off -fpic.
