1. Remove partial copy code from interpreter_completer..
---
This is another simple patch which converts interpreter_completer
to use add_completion and adds some tests to make sure that everything
is working properly.
gdb/ChangeLog
* interps.c (interpreter_completer): Use add_completion.
gdb/testsuite/ChangeLog
* gdb.base/completion.exp: Test completion limiting on
interpreter name with "interpreter-exec".
