This change syncs the tutorial with the example code document for
chapter 2. This is necessary to lookup the top level expression with the
JIT in chapter 4.

This patch fixes a minor typo in the **Kaleidoscope tutorial (Chapter
2)**.
The sentence:
“checks to see if **if** is too low”
has been corrected to:
“checks to see if **it** is too low”.
This is a documentation-only change and does not affect any semantic
behavior or code generation.
Thank you for maintaining the tutorial, and please let me know if any
further adjustments are needed.
There were quite a few places in the tutorial where the snippets were not up to date with the full code listings given. I have updated all of the ones I could find, which mostly involves changing `.` to `->` when accessing through a `std::unique_ptr`, changing `while (1)` to `while (true)`, and other such small changes.
There are still however a few places where I am not sure what to do, such as:
- Chapter 4: `ParseTopLevelExpr()` in chapter 3 sets the ProtoTypeAST
name to "", however it is referred to as "__anon_expr"
in chapter 4. Would it be required to mention this change
in chapter 4?
- Chapter 9: The code snippets refer to the top level expression as
"main", however the full code listing refers to it as
"__anon_expr". I think given the context of the chapter
it makes sense to refer to it as "main", so I have
updated the code listing to reflect that.
- Chapter 9: In chapter 9 the diff given for `HandleTopLevelExpression()`
deletes code that is not mentioned anywhere else, so I am
not sure what is to be done there.
- Miscellaneous: I don't think this is very important, however the
casing used for the first word of error messages
tends to vary between upper and lower case between
chapters and I do not know if it is worth reconciling
these differences.

Now that we've moved to C++14, we no longer need the llvm::make_unique
implementation from STLExtras.h. This patch is a mechanical replacement
of (hopefully) all the llvm::make_unique instances across the monorepo.
