We should in future do more exploration of the stochastic profiling from https://bugs.webkit.org/show_bug.cgi?id=89802. But without some sort of record-replay mode, this sort of randomness greatly increases the work required to narrow in on compiler bugs. This bug is concerned with just removing the random part of http://trac.webkit.org/changeset/121215. It still leaves the ability to periodically compute least-upper-bounds of value profiles by setting an artificially low execution count threshold.
