Homebrew bumped the version of LLVM installed with `brew install llvm`
from 3.5.1 to 3.6.0. So now users will have to tap homebrew-versions and
run `brew install llvm35` in order to get the version necessary to
install recent versions of Rubinius. The 3.5-specific `llvm-config`
becomes `llvm-config-3.5` accordingly.

The main "llvm" Homebrew package is occasionally getting updated and is
not guaranteed to be version 3.5. Right now it's 3.6, but that depends
on the version of Homebrew that someone has installed.

This lists through all installed Homebrew packages named "llvm*" and
tests each `llvm-config --version` for "3.5*" until it finds one.

Add rbx-2.5.5

Add Rubinius 2.5.4

Add jruby-1.7.20

add rbx-2.5.3

OpenJDK reports its version slightly different than Oracle Java, and
this was causing the logic in bin/ruby-build to not detect Java 7 or
higher when OpenJDK was used.

Add jruby-9.0.0.0.pre2

The checksum of the official download has changed since initial publish
time. I have compared the two downloads and it seems it was only a
single whitespace change in `.bundle/config`.

Add 'cd -' to proposed steps to upgrade ruby-build

When a target is not found, rbenv-install proposes pulling changes from
upstream. This involves changing the directory to the ruby-build checkout.

This patch adds a '&& cd -' to change the working directory back to where
we've been. Should work on at least Bash and Zsh.

Add 2.2.2, 2.1.6 and 2.0.0-p645 but they work

See https://github.com/sstephenson/ruby-build/pull/733 to get the joke.

Upgrade openssl-1.0.1m

added definition of Ruby 2.2.1

Rename jruby-9.0.0.0-pre1 to jruby-9.0.0.0.pre1
