[AST] AST structural equivalence to work internally with pairs.

Description

[AST] AST structural equivalence to work internally with pairs.

Summary:
The structural equivalence check stores now pairs of nodes in the
'from' and 'to' context instead of only the node in 'from' context
and a corresponding one in 'to' context. This is needed to handle
cases when a Decl in the 'from' context is to be compared with
multiple Decls in the 'to' context.
