The patch extends size reduction pass for MicroMIPS.
The following instructions are examined and transformed, if possible:
ADDIU instruction is transformed into 16-bit instruction ADDIUSP
ADDIU instruction is transformed into 16-bit instruction ADDIUR1SP
Function InRange is changed to avoid left shifting of negative values, since
that caused some sanitizer tests to fail (so the previous patch
