[PATCH] Remove the PR 55334 IPA-CP hack

[Martin Jambor]

Hi,

stage 1 is open so I would like to remove the PR 55334 hack as we
discussed in February so that there is incentive to handle restrict
qualifiers better when inlining and doing IPA-CP.  Thus I'll commit
the following rollback in the course of the next week (unless someone
objects but well, it's really a rollback of my previous patch).

We can continue to track the issue as PR 55334.

Let's hope I won't be adding this very same hunk again in stage 3 ;-)

Martin

	restricted pointers to arrays.
