  Log Message:
  -----------
  [AST] Fix a crash on invalid bitwidth exprs when preserving the recoveryexprs.

Summary:
If the bitwith expr contains errors, we mark the field decl invalid.

This patch also tweaks the behavior of ObjCInterfaceDecl to be consistent with
existing RecordDecl -- getObjCLayout method is only called with valid decls.
