This ammends the fix commited in https://reviews.llvm.org/D109770 / 6cf6fa6ef1c28 Comparing the number of template parameter lists with the number of template parameters is obviously wrong. Even then, the number of parameters being the same doesn't mean the templates are compatible. This change compares if the template parameters are actually equivalent. This fixes the crash, but I am not sure what is the design and intention here, this openmp template support looks too fragile. The added test case still doesn't work, but at least we don't crash now.
