Chris Fallin a0646c8d3f Account for duplicated if-block params on end op in unreachable case.
This is a close analogue to bnjbvr@'s fix in commit 518b7a7e. Similar to
that fix, this PR fixes a bug in which the Wasm translator could
misalign its value stack and either mistranslate or cause a panic with a
type-checking error.

Found via fuzzing by :decoder in SpiderMonkey (bug 1664453).
