Michael Starzinger 875ccb48ff [turbofan] Fix missing name check for keyed global load.
This fixes a missing name check for keyed property loads targeting the
global object where the feedback was warmed up with a single name. This
affects {JSLoadProperty} nodes only, syntactic global property loads via
the {JSLoadGlobal} operator are not affected.
