Insn before the error: TCRETURNri64 %RAX<kill>, 0, %RDI<kill>, 
%RAX<imp-def,dead>, %RDI<imp-def,dead>, %RSP<imp-use>, ...

Odd.  I thought TCReturn was being lowered.  At any rate can you file a bug with
the .ll file that causes this?

It should be getting lowered in emitEpilogue.  Must be a bug somewhere.
