after gdb_run_cmd, gdb_expect -> gdb_test_multiple/gdb_test

See:
  https://sourceware.org/ml/gdb-patches/2014-09/msg00404.html

We have a number of places that do gdb_run_cmd followed by gdb_expect,
when it would be better to use gdb_test_multiple or gdb_test.

This converts all that "grep gdb_run_cmd -A 2 | grep gdb_expect"
found.

Tested on x86_64 Fedora 20, native and gdbserver.
