Again, angr VEX error (especially weak support for floating operations)

[Airtnp]

And again, I cannot replay it due to limited memory. Consider adding
so.BYPASS_UNSUPPORTED_IROP
to https://github.com/hase-project/hase/blob/master/hase/symbex/tracer.py#L56

Or it would be a large fix involving angr, pyvex I guess.

This can be a fix
