@tblah @ergawy This PR is a pre-requisite for workdistribute construct implementation and lowering in flang. 
#140523 introduces "lower-workdistribute" pass which in its implementation, moves fir.allocmem which is inside omp.target region to outside (to host). So, a new op which is called from host, but allocates memory on a given omp device is required. 
So have added it in fir dialect following @ivanradanov coexecute implementation.

I would try to experiment adding this op to openmp mlir dialect as suggested and let you know if it fits this workdistribute implementation.
