qHash: update the pre-AVX512 mask to use the cacheline size
No change in behavior. But instead of trying to guess if we're going to
cross a page boundary, we check for the cacheline: if we don't cross a
cacheline boundary, then we can't cross a page boundary either. Testing
bit 4 can be implemented with a shorter instruction than a test for bit
11.
