llvm dev - Jan 2016 - [PATCH] A problem with a code sample in the tutorial LangImpl4.rst

Hello!

I was reading through the tutorial at
http://llvm.org/docs/tutorial/LangImpl4.html last night and ran into an
issue.  It was late, so I copy/pasted from the screen to test the code and
missed what turned out to be a pretty clear error in the sample code.

The literalinclude of the full code from the examples directory correctly
uses ```TheFPM->add(...)```, while the example code in the tutorial has
```TheFPM.add(...)```

The example in the tutorial also includes a function -
createBasicAliasAnalysisPass - which is not in the example file, and if I
try to add it back by hand causes the compilation to fail.

Attaching a diff with my local fixups to make it clearer (and assuming I
didn't make any fundamentally silly mistakes, I hope that's enough to
apply
- but it's been a long time since I've played with subversion).

Regards,
Peter Martini
