[turbofan] Do constant-folding of JSHasInPrototypeChain early.

We need to constant-fold JSHasInPrototypeChain nodes early during
inlining, otherwise we already miss a couple of optimization
opportunities if we wait until after typing. This moves the
constant-folding part of the JSHasInPrototypeChain lowering back to
JSNativeContextSpecialization, where it was before the changes in
https://codereview.chromium.org/2934893002 (part of
JSOrdinaryHasInstance lowering back then).

Hey Jakob,

Need to move furniture around (again). The early optimization is necessary,
otherwise we don't get the benefits during inlining.
Please take a look.

Thanks,
Benedikt
