Summary: This adds support in 'opt' to filter pass remarks emitted by optimization passes. A new flag -pass-remarks specifies which passes should emit a diagnostic when LLVMContext::emitOptimizationRemark is invoked. This will allow the front end to simply pass along the regular expression from its own -Rpass flag when launching the backend. Depends on D3227.
