Cppia - throw inside while

This seems to no longer reproduce in interp mode, but still does with jit. Here is a more stripped down sample, it is possible to demonstrate the issue without the while loop:

function other() {
	throw new haxe.Exception("hi");
}

function main() {
	function local() {
		other();
		trace("Continued past exception!");
	};

	local();
}

I've tried to investigate this issue, and it looks like the issue might be a result of local functions not being jit compiled. This means that the exception is thrown from jit -> interp -> jit, and it seems like exception handling wasn't designed in a way that considers that case. In interp mode, ctx->exception is never checked so it continues as normal until the exception is picked up again once we go back into jit world.

It seems like either of these need to be done:

1. local functions should be jit compiled, and we should check that everything is always jit compiled.
   or
2. Interp mode should consider exceptions thrown from jit mode.
