Summary:
This patch enables code generation for the MIPS II target. Pre-Mips32
targets don't have the MUL instruction, so we add the correspondent
pattern that uses the MULT/MFLO combination in order to retrieve the
product.
This is WIP as we don't support code generation for select nodes due to
the lack of conditional-move instructions.
