 C.LWSP loads a 32-bit value from memory into register {\em rd}.  It computes
 an effective address by adding the {\em zero}-extended offset, scaled by 4, to
 the stack pointer, {\tt x2}.  It expands to {\tt lw rd, offset[7:2](x2)}.

 C.LDSP is an RV64C/RV128C-only instruction that loads a 64-bit value from memory into
 register {\em rd}.  It computes its effective address by adding the
 zero-extended offset, scaled by 8, to the stack pointer, {\tt x2}.
