Revert "Temporarily Revert "Add basic loop fusion pass."" The reversion apparently deleted the test/Transforms directory. Will be re-reverting again. llvm-svn: 358552

[test][NewGVN] Use -passes=newgvn instead of -newgvn Use the new PM syntax when specifying the pipeline in regression tests previously running "opt -newgvn ..." Instead we now do "opt -passes=newgvn ..." Notice that this also changes the aa-pipeline to become the default aa-pipeline instead of just basic-aa. Since these tests haven't been explicitly requesting basic-aa in the past (compared to the test cases updated in a separate patch involving "-basic-aa -newgvn") it is assumed that the exact aa-pipeline isn't important for the validity of the test cases. An alternative could have been to add -aa-pipeline=basic-aa as well to the run lines, but that might just add clutter in case the test cases do not care about the aa-pipeline. This is another step to move away from the legacy PM syntax when specifying passes in opt. Differential Revision: https://reviews.llvm.org/D118341
