This is failing jit-tests/tests/ion/bug670484.js on IM TBPL, x64 only, with --ion --ion-eager --ion-gvn=off. It might be a register allocation bug: 9 callgeneric ([x:9 (=rcx)]) (=rdx) t=([p:7 (=rbp)], [p:8 (=rbx)]) <|@ 0 movegroup ()[=rax -> =rcx] <|@ 10 return () (=rcx) <|@ This movegroup looks bad - it clobbers the outgoing return register with something bogus.
