In 262608@main (79f0773): https://commits.webkit.org/262608@main, we landed a
speculative mitigation against an unexplained crash where an
AbstractModuleRecord
pointer somehow got the same value jsUndefined. The speculative crash mitigation
also added some Debug ASSERTs to help collect some bread crumb data about what
went wrong to lead to this crash. This patch turns these Debug ASSERTs into
RELEASE_ASSERTs to capture the telemetry data to help us diagnose this
mysterious
crash.
