Fixing several problems: GCHandle.Free() when it shouldn't; fix type …

…casting to GPU BCL methods; finding .LIB file for GPU BCL when tests aren't set up correctly. Comb test works, sort of, but only if 'swaps' variable is an Int32. This is because the meta used by JITER does not correspond to what is layed out via BUFFER. This will need to be fixed, using the meta for the GPU.
