target-mips: optimize gen_muldiv()
Optimize code generation in gen_muldiv():
- Don't do sign extension when the value is already guaranteed to be
sign extended (otherwise, results are marked as UNPREDICTABLE).
- Access the LO, HI registers directly instead of writting them through
a temporary variable.
