releaseMemory() - This member can be implemented by a pass if it wants to be able to release its memory when it is no longer needed.
The default behavior of passes is to hold onto memory for the entire duration of their lifetime (which is the entire compile time). For pipelined passes, this is not a big deal because that memory gets recycled every time the pass is invoked on another program unit. For IP passes, it is more important to free memory when it is unused.
Optionally implement this function to release pass memory when it is no longer used.
Reimplemented from llvm::Pass.

removeLoop - This removes the specified top-level loop from this loop info object.
The loop is not deleted, as it will presumably be inserted into another loop.
