Initial implementation of structural types

We infer structural types based in the usages of the attributes of a
function parameter. Currently we do it by inspecting only the body of
the function and ignore passing the parameter to subsequent calls.
Fix code completion and find usages for implicitly inferred types

Recently introduced structural types affect code insight for implicitly
inferred types. If an expression is of a structural type that has been
inferred from attributes usage then we should add implicit results we
used to infer for it before the introduction of structural types.
Suppress type and attribute inspections for structural types

Currently the type checker is not capable of checking structural types.
We have to disable these inspections until we update our type cheker.

Infer structural types for function parameters from nested calls

Using a parameter as an argument of a nested function call augments the
attribute contract for that parameter with attributes used during the
call. We use the available TypeEvalContext to keep the analysis of
nested calls fast.
