    [gdb/testsuite] Extend gdb.base/index-cache.exp

    The test-case gdb.base/index-cache.exp uses only one source file, which
    contains main.

    While doing "file $exec", in set_initial_language a symbol lookup of "m=
ain"
is
    done, causing the symtab containing main to be expanded.

    Handling of main is special, and a future optimization may skip the loo=
kup
and
    expansion.

    Reliably exercise:
    - the lookup of main, expanding the symtab containing main, by doing
      "ptype main", and
    - the lookup of another symbol, expanding a symtab not containing main,=
 by:
      - adding another source file containing function foo, and
      - doing "ptype foo".

    This triggered a segfault with target board native-extended-gdbserver,
filed
    as PR symtab/30712, but that seems to be fixed by a previous commit in =
this
    series.

    Tested on x86_64-linux.
