  1. Type inference of macros 

    This commit implements a simple type-inference pass for macros,
see HsBindgen.C.Tc.Macro. It implements a type system with:

  - variables
  - function types
  - type constructors
  - quantified types

Type inference for a macro function definition proceeds in the
following stages:

  1. constraint generation following Algorithm W, creating new
     metavariables and carrying a substitution,
  2. constraint solving: constraint simplification and defaulting
  3. quantification over remaining (undefaulted) type variables
     and remaining (unsolved) constraints.
