  Log Message:
  -----------
  [OpenMP] Add Module metadata for OpenMP compilation

This patch adds a module level metadata flag indicating that the module
was compiled with the `-fopenmp` flag. This will make it easier for
passes like OpenMPOpt to determine if it should be run.

  Log Message:
  -----------
  [OpenMP] Change OpenMPOpt to check openmp metadata

The metadata added in D102361 introduces a module flag that we can check
to determine if the module was compiled with `-fopenmp` enables. We can
now check for the precense of this instead of scanning the call graph
for OpenMP runtime functions.

Depends on D102361
