Emit special instruction for array literal + .(hash|min|max)
This commit introduces a new instruction `opt_newarray_send` which is used when there is an array literal followed by either the `hash`, `min`, or `max` method. ``` [a, b, c].hash ``` Will emit an `opt_newarray_send` instruction. This instruction falls back to a method call if the "interested" method has been monkey patched. Here are some examples of the instructions generated: ``` $ ./miniruby --dump=insns -e '[@a, @b].max' == disasm: #<ISeq:<main>@-e:1 (1,0)-(1,12)> (catch: FALSE) 0000 getinstancevariable :@a, <is:0> ( 1)[Li] 0003 getinstancevariable :@b, <is:1> 0006 opt_newarray_send 2, :max 0009 leave $ ./miniruby --dump=insns -e '[@a, @b].min' == disasm: #<ISeq:<main>@-e:1 (1,0)-(1,12)> (catch: FALSE) 0000 getinstancevariable :@a, <is:0> ( 1)[Li] 0003 getinstancevariable :@b, <is:1> 0006 opt_newarray_send 2, :min 0009 leave $ ./miniruby --dump=insns -e '[@a, @b].hash' == disasm: #<ISeq:<main>@-e:1 (1,0)-(1,13)> (catch: FALSE) 0000 getinstancevariable :@a, <is:0> ( 1)[Li] 0003 getinstancevariable :@b, <is:1> 0006 opt_newarray_send 2, :hash 0009 leave ``` [Feature #18897] [ruby-core:109147] Co-authored-by: John Hawthorn <jhawthorn@github.com>
