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] git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@53039 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
