Alexey Bataev e213f3e61a [OPENMP] Fix PR34916: Crash on mixing taskloop|tasks directives. 
If both taskloop and task directives are used at the same time in one
program, we may ran into the situation when the particular type for task
directive is reused for taskloop directives. Patch fixes this problem.
