  Log Message:
  -----------
  [Webkit Checkers][SaferCpp] Detect base-to-derived downcasts laundered through void* in MemoryUnsafeCastChecker (#200294)

Adds a matcher for static_cast<Derived*>(static_cast<void*>(base)),
which previously evaded detection because the outer cast's immediate
source expression is void*, not Base*.
