Some refactoring was needed in `Bridge.cpp`, especially in `createHostAssociateVarClone()`
and `copyHostAssociateVar()`. It was needed to be able to clone and copy variables that may
not be host associated. But I guess the refactoring was not done in the best way, so any
suggestion of how to improve it is welcome.

Also, this implementation considers only single operations inside (or not) a parallel region.
If there are other OpenMP directives that provide parallelism without using parallel, where
single can be used, these will need to be handled later.
