Fix undefined behavior in String#append_as_bytes
The UNREACHABLE macro calls __builtin_unreachable, which according to
the [GCC docs](https://gcc.gnu.org/onlinedocs/gcc/Other-Builtins.html#index-_005f_005fbuiltin_005funreachable):
> If control flow reaches the point of the __builtin_unreachable, the
> program is undefined.
But it can reach this point with the following script:
"123".append_as_bytes("123")
This can crash on some platforms with a `Trace/BPT trap: 5`.
