Enable computed goto interpreter on the host

We disabled the computed goto interpreter when compiling with clang because of
compilation issues. Since we compile with clang on the host, we used the
switch-based interpreter.

Now clang is able to compile the computed goto interpreter, we can use it by
default on the host.
