Cope with anonymous tags defined within declarators by structurally
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.
