Log:
check_tail_call
1. Removes the arbitrary check_tail_call() restriction to the final
position.
2. Fixes a bug in testing for the implicit 'null I0; null I3;
returncc' sequence -- it's 'returncc', not 'invoke'. Those instructions
are still emitted after the 'tailcall'; I wasn't sure how to remove them
without leaking memory.
3. Additionally, fixes a subtle typo in ABI_CHANGES (look closely!)
