Test that LLVM command-line flags passed via JULIA_LLVM_ARGS are
propagated to the NewPM pipeline through StandardInstrumentations:
- --print-after-all --filter-print-funcs=SomeFunction: function-level
pass (NoOpFunctionPass) respects isFunctionInPrintList()
- --print-changed=diff-quiet --filter-passes=globaldce: GlobalDCEPass
removes a dead internal global and produces a diff; filter-passes
uses the pipeline-facing name (globaldce, not GlobalDCEPass)
- Custom Julia function pass (NewPMFunctionPass) is visible to pass
instrumentation under its registered name

After I got myself confused in #551 I thought I should add some tests
showing that I was quite wrong.
