Label basic blocks with:
- their nearest enclosing structured control flow constructs.
- their nearest enclosing continue construct, if any
- their nearest enclosing loop construct, if any
A construct consists of a span of blocks in the computed block order.
It knows its parent construct, if any, and its nesting depth.

As long as a type constructor is not global the values can be non-const
which means they don't have to be constructors. This CL fixes an issue
where we incorrectly assumed the value was a constructor.

The member accessors end up being aliases in a lot of cases because you
can't have a struct that isn't an alias. This Cl unwraps the aliases at
the start of the determination for member accessors.
