Add -pass-remarks flag to 'opt'.
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.
