insns.def (opt_case_dispatch): avoid converting Infinity
Infinity cannot be written as an optimizable literal,
so it can never match a key in a CDHASH.
Avoid converting it to prevent FloatDomainError.
* insns.def (opt_case_dispatch): avoid converting Infinity
* test/ruby/test_optimization.rb (test_opt_case_dispatch_inf): new
[ruby-dev:49423] [Bug #11804]
