Reworked risv retval patch
I reworked that patch to add lp64f support and added lp64f support. I assumed
that the lp64f falls back to passing doubles in integer register, but I didn't
see that spelled out in the calling conventions
(https://riscv.org/wp-content/uploads/2015/01/riscv-calling.pdf). Is there
some document that describes the lp64f calling conventions?
