[mips] Fix ehframe-indirect.ll test.

Summary:
-check-prefix replaces the default CHECK prefix rather than adding to it and
must be explicitly re-added.

Also added the N32 cases.

Merged all except the N32 cases which seem to require later patches that
are fine on the trunk but don't seem to work on the branch.
