Message:

Remove remaining references to LLVM, and make sure comments refer to the backend as "B3" not "LLVM"

Reviewed by Saam Barati.

Source/JavaScriptCore:

I did a grep -i llvm of all of our code and did one of the following for each occurence:

• Renamed it to B3. This is appropriate when we were using "LLVM" to mean "the FTL backend".

• Removed the reference because I found it to be dead. In some cases it was a dead comment: it was telling us things about what LLVM did and that's just not relevant anymore. In other cases it was dead code that I forgot to delete in a previous patch.

• Edited the comment in some smart way. There were comments talking about what LLVM did that were still of interest. In some cases, I added a FIXME to consider changing the code below the comment on the grounds that it was written in a weird way to placate LLVM and so we can do it better now.
