[MachineOutliner] Change B instruction for tail calls to TCRETURNdi

Browse Source 
First off, this is more correct than having the B. Second off, this was making
a bot upset. This fixes that.

Update the test to include -verify-machineinstrs as well to prevent stuff like
this slipping by non debug/assert builds in the future.
