Get function to retrieve the 64 top bits of a register, stored in the gprh field of the cpu state. Set function that writes the 128-bit value at once. The access to the gprh field can not be protected at compile time to make sure it is accessed only in the 128-bit version of the processor because we have no way to indicate that the misa_mxl_max field is const. The 128-bit ISA adds ldu, lq and sq. We provide support for these instructions. Note that (a) we compute only 64-bit addresses to actually access memory, cowardly utilizing the existing address translation mechanism of QEMU, and (b) we assume for now little-endian memory accesses.
