Thanks. So much for lifting file

Hi llvm-dev! I have attached the current state of my GSoC work in patches [1] for review; this currently allows LLVM to correctly handle functions running out of stack space and variable sized stack objects. Firstly, since I think it is better to get things merged in small chunks, I'd like to have some specific feedback on where my work stands in terms of mergeability. Secondly, I had been
