ruby-1.9.3-p194 cumulative performance patch.

Patched ruby 1.9.3-p194 for 30% faster rails boot

Overview

This script installs a patched version of ruby 1.9.3-p194 with boot-time performance improvements (#66 and #68), and runtime performance improvements (#83 and #84). It also includes the new backported GC from ruby-trunk.

Many thanks to funny-falcon for the performance patches.
