fixes #23177
`changeType` doesn't perform range checks to see if the expression fits
the new type [if the old type is the same as the new
type](62d8ca4306/compiler/semexprs.nim (L633)).
For `nkIntLit`, we previously set the type to the concrete base of the
expected type first, then call `changeType`, which works for things like
range types but not bare types of smaller bit size like `int8`. Now we
don't set the type (so the type is nil), and `changeType` performs the
range check when the type is unset (nil).
