Fix new clang warnings.
2019-08-27 Martin Liska <mliska@suse.cz> * cgraph.c (cgraph_node::remove): Remove dead assignment before loop. * config/i386/i386-features.c (scalar_chain::emit_conversion_insns): Enclose in anonymous namespace. * config/i386/x86-tune-costs.h (struct processor_costs): Wrap hard_register initialization in braces. * tree-vrp.h (value_range_base::supports_type_p): Return false for function with boolean return type.
