* Fixed a memory leak with shared variable (we kept a pointer to the original value)

* Alloc, GpuAlloc are not always pre-computed(constant_folding optimization) at compile time if all its inputs are constants
* The keys in our cache now store the hash of constants and not the constant values themselves. This is significantly more efficient for big constant arrays.
