e11354c0a4 [Tests] Remove explicit -enable-mssa-loop-dependency options (NFC) 
This is enabled by default. Drop explicit uses in preparation for
removing the option.

Also drop RUN lines that are now the same (typically modulo a
-verify-memoryssa option).

The reversion apparently deleted the test/Transforms directory.

Will be re-reverting again.
