Description:
MIPS64: Improve long branches utilizing code range.
Improves code size of generated regexp in TestSizeOfRegExpCode test by 33%.
Execution time of the same test improved by ~10%.
Utilizing code range for mips64 enable us to use J/JAL
instructions for long branches.
Further in follow-up CL we could optimize calls.
