[RISCV] Add combine for shadd family of instructions. (#130829)
For example for the following situation:
%6:gpr = SLLI %2:gpr, 2
%7:gpr = ADDI killed %6:gpr, 24
%8:gpr = ADD %0:gpr, %7:gpr
If we swap the two add instrucions we can merge the shift and add. The
final code will look something like this:
%7 = SH2ADD %0, %2
%8 = ADDI %7, 24
