This PR includes the following commits:

  • New test for MPI_Double_Int datatype with MPI_Allreduce: MANA fails to resolve MPI_Double_Int for a call to MPI_Allreduce CoMD software. This commit adds a small and faster toy program to MANA's test directory for quickly filtering similar failures in future.
  • Fixed upper_to_lower_constants lookup for special(negative) Datatypes: Special Datatypes are defined in MPI library for 'struct' type datatypes, defined as negative constant values. This commit aims to maintain integrity of these special(negative) datatype when passed in function calls.
