GCOV: introduce --json-format.

2018-10-29  Martin Liska  <mliska@suse.cz>

	* Makefile.in: Make dependency to json.o.
	* doc/gcov.texi: Document new JSON format, remove
	old intermediate format documentation.
	* gcov.c (struct function_info): Come up with m_name and
	m_demangled_name.
	(function_info::function_info): Initialize it.
	(function_info::~function_info): Release it.
	(main): Rename flag_intermediate_format to flag_json_format.
	(print_usage): Describe --json-format.
	(process_args): Set flag_json_format.
	(output_intermediate_line): Remove.
	(output_intermediate_json_line): Likewise.
	(get_gcov_intermediate_filename): Return new extension
	".gcov.json.gz".
	(output_intermediate_file): Implement JSON emission.
	(output_json_intermediate_file): Implement JSON emission.
	(generate_results): Use ::get_name for function name.
	Handle JSON output file.
	(read_graph_file): Use ::get_name instead of cplus_demangle.
	(read_count_file): Likewise.
	(solve_flow_graph): Likewise.
	(add_line_counts): Likewise.
	(accumulate_line_counts): Use new flag_json_format.
	(output_function_details): Use ::get_name instead of cplus_demangle.
	(output_lines): Likewise.
	* json.cc (test_writing_literals): Add new tests.
	* json.h (class literal): Add new boolean constructor.

	* g++.dg/gcov/gcov-8.C: Do not check intermediate format.
	* lib/gcov.exp: Remove legacy verify-intermediate.
