riscv-trap-handling: Add functionality, prevent stack corruption
Trap handling code was bugged in that it loaded in the wrong stack
pointer, overwriting the space the processor uses to talk to its host
for doing device requests. Fix this issue, as well as add support for
handling misaligned loads the same way we handle misaligned stores.
