OK. For this I propose to insert calls to libgomp (gnuopenmp) or the mpc 
openmp library.

If you check out mpc you will find explanations how to use it to create 
OpenMP constructs by hand in a header file called mpcomp_abi.h located 
inside the mpc/MPC_OpenMP/include directory.
As a starter I would write C code that does what you expect and compile 
it to LLVM-IR to see how the libraries are inserted in the LLVM-IR.
