[mips] [IAS] Slightly improve shift instruction generation in expandLoadImm.
Summary: Generate one DSLL32 of 0 instead of two consecutive DSLL of 16. In order to do this I had to change createLShiftOri's template argument from a bool to an unsigned. This also gave me the opportunity to rewrite the mips64-expansions.s test, as it was testing the same cases multiple times and skipping over other cases. It was also somewhat unreadable, as the CHECK lines were grouped in a huge block of text at the beginning of the file.
