[PATCH 2/2] Add more entries to the C++ get_std_name_hint array

[Jonathan Wakely <jwakely at redhat dot com>]

This adds some commonly-used C++11/14 names, and some new C++17/20
names. The latter aren't available when using the -std=gnu++14
default, so the fix-it suggesting to use a newer dialect is helpful.

	* name-lookup.c (get_std_name_hint): Add more entries.

Tested x86_64-linux. OK for trunk?

    Add more entries to the C++ get_std_name_hint array
    
            * name-lookup.c (get_std_name_hint): Add more entries.
