Fix crash when setting breakpoint condition
gdb could crash when setting a breakpoint condition on a breakpoint
when using the Ada language. The problem occurred because the
ada_evaluate_subexp would try to evaluate the array to compute its
attributes, but evaluating can't really be done at this time.
This patch fixes the problem by arranging not to try to evaluate in
EVAL_AVOID_SIDE_EFFECTS mode when computing an attribute.
Tested on x86-64 Fedora 29. Because this is Ada-specific, and because
Joel approved it internally, I am checking it in.
