04:33 PM Ruby Revision 6e5e6a40 (git): Deduplicate objects efficiently when dumping iseq to binary

We were inefficient in cases where there are a lot of duplicates due to
the use of linear search. Use a hash table instead.
These cases are not that rare in the wild.

01:42 PM Ruby Feature #16505 (Closed): Improve preformance of `RubyVM::InstructionSequence#to_binary`

## Abstract
Within #to_binary, deduplication of objects output to binary is performed, but the current implementation is achieved by a linear search of an array of objects (=`obj_list`). (https://github.com/ruby/ruby/blob/e288632f22b18b... NagayamaRyoga (Nagayama Ryoga)
