[LLVMdev] Incorrect code generated for arm64

> Do you think it’s worth getting into 3.6.1? Is the bug limited to tail call stuff (so any functions that make use of the extended vec3 will be fine - that’s my usual case), or does it potentially have wider effects?

I think Tom said he'd stopped taking nominations for 3.6.1. I'll try
to remember to put it on the branch after that if we do a 3.6.2
though.
