AssemblyScript: `Console.log` of string literal panics

[radu-matei]

This is a weird error, so I'm opening it sooner rather than later, even with very little info.
Stumbled across this while trying to decode a header value, and it turns out that sometimes trying to Console.log (or Console.write) a string panics.

I haven't tested this outside of the current project, which is why I'm not opening this issue in as-wasi yet.

In short:

let y = "testofastringliteral";
Console.log(y);

The weird part is that Console.log("value" + y); will run successfully.

However, the result is that trying to just print a header value simply panics in my WIP branch.
I'll try to reproduce this and update the issue.

I hit this again working on #58.
I will try updating the AssemblyScript compiler version and the local dependency, but this is so weird.

I am going to assume this is related somehow to AssemblyScript/assemblyscript#2099
