[commit 2/2] Remove AT_SYMBOL

[Joel Brobecker <brobecker@adacore.com>]

Now that this method is no longer used by any architecture,
we can remove its support.

gdb/ChangeLog:

        * infcall.c (call_function_by_hand): Remove AT_SYMBOL handling.
        * inferior.h (AT_SYMBOL): Delete.

Will commit as soon as the mips-tdep patch gets checked in.
