Update s2wasm for reordered call_indirect (#802)

* Update s2wasm for reordered call_indirect

https://reviews.llvm.org/D25708 fixed call_indirect for 0xc by
reordering the operands. s2wasm needs to be aware of that too.

* Update llvm_autogenerated tests

* Update torture-s tests

* run auto_update_tests

* update handwritten dot_s test that had call_indirect with args
