This adds a GetObjectFileInterface callback member to StaticLibraryDefinitionGenerator, and adds an optional argument for initializing that member to StaticLibraryDefinitionGenerator's named constructors. If not supplied, it will default to getObjectFileInterface from ObjectFileInterface.h. To enable testing a `-hidden-l<x>` option is added to the llvm-jitlink tool. This allows archives to be loaded with all contained symbol visibilities demoted to hidden. The ObjectLinkingLayer::setOverrideObjectFlagsWithResponsibilityFlags method is (belatedly) hooked up, and enabled in llvm-jitlink when `-hidden-l<x>` is used so that the demotion is also applied at symbol resolution time (avoiding any "mismatched symbol flags" crashes).
