[Debugify] Preserve analyses in -check-debugify The -check-debugify pass should preserve all analyses. Otherwise, it may invalidate an optional analysis and inadvertently alter codegen. The test case is reduced from deopt-bundle.ll. The result of `opt -O1` on this file would differ when -debugify-each was toggled. That happened because CheckDebugify failed to preserve GlobalsAA. Thanks to Davide Italiano for his help chasing this down! llvm-svn: 333959

[opt] Introduce -strip-named-metadata This renames and generalizes -strip-module-flags to erase all named metadata from a module. This makes it easier to diff IR. llvm-svn: 333977
