create_pgo_func_name_var	Calls llvm::createPGOFuncNameVar() with the given function instance’s mangled function name. The LLVM API returns an llvm::GlobalVariable containing the function name, with the specific variable name and linkage required by LLVM InstrProf source-based coverage instrumentation. Use `bx.get_pgo_func_name_var()` to ensure the variable is only created once per `Instance`.
