Need to pass "--frame N" to some gdb/mi commands.

[epasveer]

When adding a breakpoint/printpoint, the "--frame N" argument needs to be provided if the user is trying to set a point with just the line number.

The gdb doc says:

 -stack-select-frame framenum
 This command in deprecated in favor of passing the ‘--frame’ option to every command.

gdbmi no longer supports:

-stack-select-frame %1

So use the non-gdbmi version:

frame %1

For now, this is better than maintaining the current stack frame. Also, it looks like inserting a breakpoint doesn't support a stackframe, anyways.
