This is the first patch in a series intended for removing flag -enable-new-pm=0 from lit tests. This is part of a bigger effort of completely removing legacy code related to legacy pass manager in favor of currently default new pass manager. In this patch flag has been removed only from tests where no significant change has been required because checks has been duplicated for both PMs. Reviewed By: fhahn Differential Revision: https://reviews.llvm.org/D134150
