Very nice.  Here's a couple comments on the first 6 chapters:
"We handle comments by skipping to the end of the line and then
returning the next comment."

Shouldn't this say "returning the next comment"?

I was a bit confused at first because the AST node classes are called
ASTs. Instead of saying "ExprAST node" all the time, who not just call
the class ExprNode or ExprAstNode?

  case '<':
    L = Builder.CreateFCmpULT(L, R, "multmp");
Should this be something like "cmptmp"?

Also, you mention zero-argument functions, but it doesn't look like
you can parse function calls with zero arguments.

At this point, you are probably starting to think "on no!
Should be "Oh no"

There's no link to the next chapter at the end of this chapter.
