comparing their types under the assumption that they are equivalent,
rather than importing the types and then checking for compatibility. A
few minor tweaks here:
  - Teach structural matching to handle compatibility between
  function types with prototypes and those without prototypes.
  - Teach structural matching that an incomplete record decl is the
  same as any other record decl with the same name.
  - Keep track of pairs of declarations that we have already checked
  (but failed to find as structurally matching), so we don't emit
  diagnostics repeatedly.
  - When importing a typedef of an anonymous tag, be sure to link the
  imported tag type to its typedef.

With these changes, we survive a repeated import of <stdlib.h> and
<stdio.h>. Alas, the ASTNodeImporter is getting a little grotty.

Tell ASTMerge to merge every declaration it sees, rather than cherry-picking those declarations that we know will work.

two types in different AST contexts are equivalent. Rather than
transforming the type from one context into the other context, we
perform a deep structural comparison of the types. This change
addresses a serious problem with recursive data types like

  struct ListNode {
    int value;
    struct ListNode *Next;
  } xList;

property diagnostics for properties declared in class extensions
multiple times (radar 7629420) and for future use.

of operating on each code decl.  This exposes two flaws in AnalysisConsumer
that should eventually be fixed:

(1) It is not possible to associate multiple "actions" with a single
    command line argument.  This will require the notion of an
	"analysis" group, and possibly tablegen support.  (although eventually
    we want to support dynamically loading analyses as well)

(2) AnalysisConsumer may not actually be scanning the declarations in namespaces.
    We'll experiment first in LLVMConventionsChecker before changing the
    behavior in AnalysisConsumer.
