This is one last remaining instrumentatation related structure that needs to be migrate to use the centralized template definition. With this change, instrumentation code related to coverage module header will be kept in sync with the coverage mapping reader. The remaining code which makes implicit assumption about covmap control structure layout in the the lowering pass will cleaned up in a different patch. This patch is not intended to have no functional change. llvm-svn: 256714
