[stubs] Store typeof string on Oddballs.

[stubs] Store typeof string on Oddballs.

First step to simplify the TypeofStub. This is similar to the
optimization that we use for ToNumber and ToString on Oddballs already.

Hey Yang,

As discussed offline: I'm going to simplify the TypeofStub. This is the obvious
optimization for Oddball; the next thing is to target SIMD types.

Please take a look.

Thanks,
Benedikt
