Add native gchelper support for 64 bits RISC-V RV64I targets. Now that RV64 is under CI, this also enables platform-specific ghelper in the Unix port. Also changes the data type holding the register contents to something more appropriate, so in the remote eventuality somebody wants to use this with RV128 all they have to do is update the `__riscv_xlen` check.
