Changes (by bgamari):

 * status:  new => closed
 * resolution:   => fixed
 * milestone:   => 8.0.1


Comment:

 If I'm not mistaken this is resolved,

  * `-fwarn-tabs` is gone
  * `-fwarn-monomorphism-restriction` has been resuscitated
  * `-fwarn-unrecognised-pragmas` no longer exists
  * `-XAlternativeLayoutRule` and friends is handled in #11359
  * `-fwarn-amp` will be handled in due time (created #11477 to track this)
