[mips] Add RuntimeDyld tests for currently supported O32 relocations.

change %/T to %T in order to be consistent and avoid needless canonicalization.

Do we want to keep these lines (disabled) for future reference?

I've made this change but I may have to change it back if the windows buildbots complain.

I'll delete them for now and bring them back when big-endian works.
