With this patch, handwriting version comparisons become a little bit easier.

SomeGem.version <=> Gem::Version.new('1.3')

SomeGem.version <=> '1.3'

Previously Time.now was switched to use Time.new as it added support for
the in: argument. Unfortunately because Class#new is a cfunc this
requires always allocating a Hash.
This commit switches Time.now back to using a builtin time_s_now. This
avoids the extra Hash allocation and is about 3x faster.

This adds support for passing keyword arguments to cfuncs. This is done
by calling a helper method to create the hash from the top N values on
the stack (determined by the callinfo) and then moving that value onto
the stack.
The word "specification" can be confusing as it might make readers
assume that the Ruby Spec Suite is a specification similar to an ISO
specification. Avoid the word and link to the project so curious parties
could read more about the project.
