If a defined local is referenced to in the type of a declared one (e.g. in
a `sizeof` expression as part of an array length), the `Local_init` will put
its actual definition after the declaration (which occurs at the beginning of
the block, resulting in at least pretty-printing unparsable code. We generate
undeclared temp variables of the same type to overcome the issue, like in

they can appear before their `Local_init`, e.g. in a `SizeOfE` in the
size expression of a local array. Furthermore, we weren't really checking that
declared locals weren't used before the block in which they were supposed to
appear.

from a dependency point of view, this make more sense.
