#195272 added a reference to opts::Hugify from LongJmp.cpp. This
broke shared-library builds because LLVMBOLTPasses does not link
against LLVMBOLTRuntimeLibs, where the option was previously defined.
Move the opts::Hugify definition to CommandLineOpts.cpp, alongside
the other global BOLT command-line options. This keeps the option
available to LLVMBOLTPasses through its existing LLVMBOLTUtils
dependency without adding a dependency on the runtime library layer.
