Filter: Better constant promotion
...
We use constant promotion from IPv4 to Router-ID values, as they have
same literals. Instead of ad-hoc code in filter instructions, add
constant promotion code to parse-time typecheck code.

Most expressions can be type-validated in parse time. It is not
strong enough to eliminate runtime checks, but at least one gets
errors immediately during reconfigure.

Function bodies were compared in post-parse time, yet the result was not
used and the functions were incorrectly considered the same as before.
Now the result is used to reload affected protocols.
