Optimization transformations are intentionally disabled by the 'optnone' function attribute. Therefore do not warn if transformation metadata is still present. Using the legacy pass manager structure, the `skipFunction` method takes care for the optnone attribute (already called before this patch). For the new pass manager, there is no equivalent, so we check for the 'optnone' attribute manually. Differential Revision: https://reviews.llvm.org/D55690 llvm-svn: 349184
