[MachineFunctionPass] Support -filter-passes for -print-changed -filter-passes specifies a `PassID` (a lower-case dashed-separated pass name, also used by -print-after, -stop-after, etc) instead of a CamelCasePass. `-filter-passes=CamelCaseNewPMPass` seems like a workaround for new PM passes before we can use lower-case dashed-separated pass names (as used by `-passes=`). Example: ``` # getPassName() is "IRTranslator". PassID is "irtranslator" llc -mtriple=aarch64 -print-changed -filter-passes=irtranslator < print-changed-machine.ll ``` Close https://github.com/llvm/llvm-project/issues/57453 Reviewed By: aeubanks Differential Revision: https://reviews.llvm.org/D133055
