The following gets rid of the idea that we should prevent setjmp
like calls from popping up in uncontrolled way in the IL for now.
The solution is probably to handle it similar as noreturn has
the ctrl-altering flag on stmts, but use another flag, for example
ctrl-receiving which would also make sure the stmt is first.

When we have a closure expression that captures a parent function's
variable we must setup the closure data to contain this. Ignoring
moveability and mutability requires for now, this patch creates the closure
structure with fields for each of the captured variables. When it comes to
compilation of the closure expression in order to support nested closures
we must setup a context of implicit mappings so that for all path
resolution we hit this implicit closure mappings lookups code before any
lookup_var_decl as this decl will not exist so the order here is important
during path resolution which is a similar problem to match expression
destructuring.

When we have a closure block referencing variables in a parent function,
we must track what these are. We do this by having a context of closures
so if we have a variable reference and its declared in a rib whose node id
is less than the node id of the closure's node id we know it must be a
captured variable. We also need to iterate all possible closure contexts
as we might be in the case of a nested closure.
