 - Better resolving of the PHI functions. Today, we always generate MOV

 This leads to code duplication. Also some messages used by OpenCL (untyped reads
 and writes) are not properly decoded yet.

 Parts of the code leaks memory when exceptions are used. There are some pointers
 to track and replace with std::unique_ptr. Note that we also add a custom memory
