assertLessThan() actually does the opposite of what it advertises.
It's only through luck that existing asserts have not failed
before. This changes assertLessThan to actually assert that the
value is less than something.

We used to have a separate `directive` instruction for instantiating
directives. However, such an instruction requires that directives
are created in the correct order, which would require that template
compiler would have knowledge of all dependent directives. This
would break template compilation locality principle.
This change only changes the APIs to expected form but does
not change the semantics. The semantics will need to be corrected
in subsequent commits. The semantic change needed is to
resolve the directive instantiation error at runtime based on
injection dependencies.
