07ba7ad073 Move the is_pregenerated flag so it does not overlap other flags. 
Remove the before-or-after InstanceOf stub rule, which was too
subtle and lacked checking ssertions.
Unify the way the CEntry stub is pregenerated so that it is done
in the same way.

27e1a8d414 Improve our simple elimination of hole checks. 
Currently we avoid checking for the hole value after array loads, if the
result is only used by instructions that definitely deoptimize in case
of the hole value (HChange instructions).

This change performs the same procedure for loading from deleteable/read-only
global variable where we can also avoid the check in the same cases.
