eval.c: suppress warnings
* eval.c (exc_setup_message): setup exception message as an
exception instance, and a cause from a previous exception.
split from setup_exception to suppress a warning when
RUBY_USE_SETJMPEX is enabled.
* eval.c (setup_exception): make state volatile to suppress a
warning too.
