Fix terminology of snapshot saving in literals and main

In case of literals and in main, snapshot saving is incorrectly
named dumping. Elsewhere in the code, 'dump' functions output debug
data (even literals have a `lit_dump_literals` debug function). To
help distinction and to align terminologies, snapshot saving
functions of literals and command line options of main are also
re-named 'save'.
