To avoid recursion cost we now more aggressively inline. The many added branches for this shortcut to work can easily hurt performance as well.

Very large allocations can cause timeouts or crashes on TSAN bots. This test checks the handling of arrays with length > MaxSmi, so allocates a very large array. It's unlikely that TSAN will find anything interesting here that other bots won't catch, so disabling the test.

These two builtins are a special case in that their calling convention must be kept in-sync since they are both generated from Generate_CallOrConstructVarargs. ConstructVarargs in particular used all available registers. In order to free ebx, the calling convention is changed to pass the last argument on the stack. As part of this change, the order of the last two arguments is swapped since the stack parameter must be tagged.

This fixes a crash with a predicate used during stack unwinding of WebAssembly frames during exception handling. The predicate caused an observable side-effect in JavaScript during unwinding, code that is inherently unhandlified and is not allowed to be observable. The fix actually just removes the entire predicate. This is because the updated proposal causes all JavaScript exceptions to participate in WebAssembly exception handling, allowing modelling of "finally" language constructs to perform cleanup independent of the embedders exception details.
