Description
When tracePrimEnabled, DPH programs will print out what flat array
primitives they're using at runtime. See tracePrim for details.

tracePrim :: TracePrim -> a -> aSource
Print tracing information to console.
This function is used to wrap the calls to DPH primitives defined
in dph-prim-par:Data.Array.Parallel.Unlifted
Tracing is only enabled when tracePrimEnabled is True.
otherwise it's a no-op.
Records information about the use of a flat array primitive.
These are the operator names that the vectoriser introduces.
The actual implementation of each operator varies depending on what DPH primitive library is being used.
We only trace operators that are at least O(n) in complexity.
