Revert of track global accesses to constant types (patchset #15 id:280001 of https://codereview.chromium.org/1062163005/)

Reason for revert:
[Sheriff] Speculative revert for maybe breaking layout tests, e.g.
http://build.chromium.org/p/client.v8/builders/V8-Blink%20Linux%2032/builds/2589

Will reland if it doesn't help.
