Revert "i965: fix problem with constant out of bounds access (v2)"
This reverts commit 98dfd59a0445666060c97b0dccaf0e9f030b547a.
The patch was clearly not Piglit tested, as it caused at least 225
tests to start crashing with assertion failures. That was before my
desktop tanked and the test run died completely.
