This is the orignal patch + a check that LLVM_BUILD_EXAMPLES is enabled before adding a dependency on the 'Bye' example pass. Original summary: Add cli options for new passmanager plugin support to lld. Currently it is not possible to load dynamic NewPM plugins with lld. This is an incremental update to D76866. While that patch only added cli options for llvm-lto2, this adds them for lld as well. This is especially useful for running dynamic plugins on the linux kernel with LTO.
