_ is now an identifier that is always valid to write to, but never to read from. It can also be shadowed freely.

Closes #876.

It looks like LLVM 3.6 isn't available anymore in Homebrew in the OSX Travis CI.

@SeanTAllen Unfortunately it is still failing. #1498 and #1395 also failed because of this.

@Praetonus It looks like only 3.7, 3.8, 3.9 are available via homebrew anymore.

Looks like we should disable 3.6 for OSX and state that 3.6 is no longer supported on it.

This passed except for LLVM 3.6 on OSX which we are deprecating.

Merging.
