/* CONJECTURE_ASSERT is only used to facilitate on-going analysis work to test conjectures

   extended testing.

   If the conjecture is proven false, then the CONJECTURE_ASSERT should either be removed or
   updated to test a new conjecture. If the conjecture is proven true, the CONJECTURE_ASSERT
   should either be promoted to an ASSERT or RELEASE_ASSERT as appropriate, or removed if
   deemed of low value.

   The number of CONJECTURE_ASSERTs should not be growing unboundedly, and they should not
   stay in the codebase perpetually.

   There is no EWS coverage for CONJECTURE_ASSERTs. So, if you add one, you are responsible
   for making sure it builds with ENABLE_CONJECTURE_ASSERT set to 1, and for running tests on
   your build to make sure that the assertion is not immediately failing.

   To run with CONJECTURE_ASSERTs enabled, you also need to define the environmental variable
   ENABLE_WEBKIT_CONJECTURE_ASSERT. Otherwise, the assertion will not be tested.
