Jakob Stoklund Olesen 0d141f867d The early if conversion pass is ready to be used as an opt-in.
Enable the pass by default for targets that request it, and change the
-enable-early-ifcvt to the opposite -disable-early-ifcvt.

There are still some x86 regressions when enabling early if-conversion
because of the missing machine models. Disable the pass for x86 until
machine models are added.
