[PATCH 0/3] favor newer Rubies for performance

[Eric Wong <e@80x24.org>]

* [PATCH 1/3] generate response status strings dynamically

  This unfortunately introduces a minor performance regression.
  However, it is unlikely to be noticeable in real-world apps.

* [PATCH 2/3] reduce constants and optimize for Ruby 2.2+

  This appears to recover the performance lost in 1/3 when doing
  informal benchmarks on a private app (persistent connections
  enabled).

* [PATCH 3/3] http_response: reduce bytecode size

  This generates less bytecode when checking with
  RubyVM::InstructionSequence.compile
