Set max_iv_count (used for object shapes) based on inline cachesHEADmaster
With this change, we're storing the iv name on an inline cache on setinstancevariable instructions. This allows us to check the inline cache to count instance variables set in initialize and give us an estimate of iv capacity for an object. For the purpose of estimating the number of instance variables required for an object, we're assuming that all initialize methods will call `super`. This change allows us to estimate the number of instance variables required without disassembling instruction sequences. Co-Authored-By: Aaron Patterson <tenderlove@ruby-lang.org>
