  {- Work around #23537
  
  On 32 bit systems, GHC's codegen around 64 bit numbers used to be incomplete
  before GHC 9.10. This led to panics mentioning missing cases in iselExpr64.
  Now that GHC uses Word64 for its uniques, these panics have started popping up
  whenever a unique is compared to many other uniques in one function. As a
  workaround we use these two functions which are not inlined, on 32 bit systems
  and if compiled with versions before GHC 9.9, thus preventing the panics.
