Support newer versions of llvm

[jeremysalwen]

llvm3.4 is getting old, and code written against newer compiler/standards versions fails to compile with clang3.4. Moving to a newer version of llvm would help keep this tool alive. Feature request of course :)

Has there been any indication of updating it? I wanted to test some parts of my thesis with the program, but found myself unable to compile STACK:

I just wanted to use STACK on a large community project (I remember it being useful a few years back) but then saw this issue. I guess there is no effort to keep this tool alive?

I tried last year, but it was not fully finished, then I'm busy aftet that month...
