Fix rewriter issues
Allow pat_lits rewrite to map L_unit to wildcard patterns, rather than introducing eq_unit tests as guards. Add a fold_function and fold_funcl functions in rewriter.ml that apply the pattern and expression algebras to top-level functions, which means that they correctly get applied to top-level function patterns when they are used. Currently modifying the re-writing passes to do this introduces some bugs which needs investigated further. The current situation is that top-level patterns and patterns elsewhere are often treated differently because rewrite_exp doesn't (and indeed cannot, due to how the re-writer is structured) rewrite top level patterns. Fix pattern completeness check for unit literals Fix a bug in Sail->ANF transform where blocks were always annotated with type unit incorrectly. This caused issues in pattern literal re-writes where the guard was a block returning a boolean. A test case for this is added as test/c/and_block.sail. Fix a bug caused by nested polymorphic function calls and matching in top-level patterns. Test case is test/c/tl_poly_match.sail. Pass location info through codegen_conversion for better error reporting
