Original commit message:
Since the per-context random number generator is now
properly seeded upon context creation, we do not need
to check for lazy-initialization anymore, and so we
can implement the HRandom instruction w/o having to
call into the C function (which means we don't need
to MarkAsCall anymore).

Implement in-place rehashing of HashTable. · 0e8e0030

ulan@chromium.org authored Sep 12, 2013

The algorithm puts elements into correct positions in multiple iterations.
On the first iteration it tries to put elements at entries specified by
their first hash probe. On the second iteration -- by the second
hash probe, and so on. Overall it does O(k*n) memory accesses, where
k is the maximum number of probes required for an element and n is the
capacity of the hash table. The expectation is that k will be small.
