[PATCH 1/2] [PR symtab/17602] Split up gdb.cp/anon-ns.cc

[Doug Evans <dje@google.com>]

Hi.

A lot of our tests live in just one source file which is bad
because gdb expands the symbol table with main() at startup.
Thus such tests exercise less than they could.

This patch splits up the gdb.cp/anon-ns test,
it was useful in diagnosing pr 17602.
