  -----------
  [clang][WebAssembly] Initial support for reference type funcref in clang

This is the funcref counterpart to 890146b. We introduce a new attribute
that marks a function pointer as a funcref. It also implements builtin
__builtin_wasm_ref_null_func(), that returns a null funcref value.
