Added project ideas from Chen Ding and Rahman Lavaee.

Added two projects in the list of projects that use LLVM.  Both are related
to Chen Ding's locality theory work with LLVM.  One is a project to optimize
code layout dynamically using the LLVM JIT.  The other is to modify structure
fields to obtain better cache performance.

+  Implement an on-demand function relocator in the LLVM JIT. This can help
+  improve code locality using runtime profiling information. The idea is to use
+  a relocation table for every function.  The relocation entries need to be
+  updated upon every function relocation (take a look at
+  <a href="https://people.cs.umass.edu/~emery/pubs/stabilizer-asplos13.pdf">
+  this article</a>).
+  A (per-function) basic block reordering would be a useful extension.
