Revert "Reland^3 "[turbofan] Use feedback when reducing global loads/stores.""

This reverts commit 8683116e64335a99ecc403c509587410db070cd1.

Reason for revert: There's a bug in the StoreGlobalIC that causes regressions in combination with this CL (observable in Chrome but
not in d8).

Original change's description:
> Reland^3 "[turbofan] Use feedback when reducing global loads/stores."
>
> This is a reland of 2d2c1374929c7ff41bed6526103ba6217009057a without
> changes. Offending chromium tests have been modified.
