insns.def (opt_case_dispatch): check Float#=== redefinition

The missing check for Float#=== redefinition was noticed while
working on enhancing optimized case dispatch for nil/true/false
in [ruby-core:71818] https://bugs.ruby-lang.org/issues/11769

So no, I don't normally redefine core classes like this :P

* insns.def (opt_case_dispatch): check Float#=== redefinition
* test/ruby/test_optimization.rb (test_opt_case_dispatch): new
  [ruby-core:71920] [Bug #11784]
