Seeing the symmetry between set_int_value() and do_get_int_value(),
I tend to agree that it would be easier to remember what the latter
does if it were named get_int_value().

I am not so sure about _or_die(), though.  The only kind of error
the current get_int_value() detects and acts on is the mismatched
precision bug, which is a programmer error; there is no "die" but
we call "BUG".

get_int_value_with_precision_check() is quite a mouthful, but it is
known that I am bad at naming X-<, so I dunno.
