Heejin Ahn bcac389fb2 [WebAssembly] Fix fixEndsAtEndOfFunction for try-catch ... When the function return type is non-void and `end` instructions are at the very end of a function, CFGStackify's `fixEndsAtEndOfFunction` function fixes the corresponding block/loop/try's type to match the function's return type. This is applied to consecutive `end` markers at the end of a function. For example, when the function return type is `i32`, ``` block i32 ;; return type is fixed to i32 ... loop i32 ;; return type is fixed to i32 ... end_loop end_block end_function ``` But try-catch is a little different, because it consists of two parts: a try part and a catch part, and both parts' return type should satisfy the function's return type. Which means, ``` try i32 ;; return type is fixed to i32 ... block i32 ;; this should be changed i32 too! ... end_block catch ... end_try end_function ``` As you can see in this example, it is not sufficient to only `end` instructions at the end of a function; in case of `try`, we should check instructions before `catch`es, in case their corresponding `try`'s type has been fixed. This changes `fixEndsAtEndOfFunction`'s algorithm to use a worklist that contains a reverse iterator, each of which is a starting point for a new backward `end` instruction search.
