[bugpoint] Add a named metadata (+their operands) reducer Summary: We frequently run bugpoint on a linked module that consists of all modules we create while jitting the julia standard library. This module has a very large number of compile units (10000+) in `llvm.dbg.cu`, which didn't get reduced at all, requiring manual post processing. This is an attempt to have bugpoint go through and attempt to reduce the number of global named metadata nodes as well as their operands, to cut down the number of roots for such metadata.
