[turbofan] Remove untested no-deoptimization code path from JSGlobalObjectSpecialization.

We don't have proper test coverage for the no-deoptimization code paths
in the JSGlobalObjectSpecialization reducer, and we will properly never
have any use for that code, so it just adds complexity and code that
likely breaks over time (as its untested).

Hey Jaro,

Untested code is likely broken code. Removing the potential dead code simplifies
the live code.
Please take a look.

Thanks,
Benedikt
