[RFA,2/4] Change the as_*_interp functions to use dynamic_cast
Commit Message
This changes the various as_*_interp functions to be implemented using
dynamic_cast. I believe this is a small improvement, because it is
more typesafe -- the C++ runtime does the type-checking for us.
ChangeLog
2018-04-29 Tom Tromey <tom@tromey.com>
* tui/tui-interp.c (as_tui_interp): Use dynamic_cast.
* mi/mi-interp.c (as_mi_interp): Use dynamic_cast.
* cli/cli-interp.c (as_cli_interp): Use dynamic_cast.
