John Stiles e3f85e07fa Add improved regression test for oss-fuzz:36655. 
Most of the code generated by the fuzzer is nonsense, but there is a
method to its madness. The crash is only triggered under specific
conditions:
- The runtime effect has enough helper functions to mostly fill up the
  call graph hash-map. It won't rehash until it gets close to capacity.
- There must be several calls to built-in functions, in order to add
  elements to the call graph to force a rehash.

The fuzzer-generated code manages to satisfy both these requirements.
