Feature #12639: Speed up require in RubyGems by 5x
https://bugs.ruby-lang.org/issues/12639#change-73135

* Author: segiddins (Samuel Giddins)
* Status: Assigned
* Priority: Normal
* Assignee: hsbt (Hiroshi SHIBATA)
* Target version: 
----------------------------------------
This patch makes requiring an already-loaded file approximated 5x faster when the RubyGems mixin for require is present.
Benchmarked via the following script:

~~~ ruby
require "rubygems"
require "benchmark/ips"

Benchmark.ips do |x|
	x.report("ruby") { gem_original_require "rubygems" }
	x.report("rubygems") { require "rubygems" }
	
	x.compare!
end
~~~

I understand that it's not ideal to add new global functions, and I'd appreciate guidance on where else I could expose this functionality to ruby code.

Thanks :)
