Merge pull request #15440 from everton1984:new_integral_tests

* Adding all possible data type interactions to the perf tests since some
use SIMD acceleration and others do not.

* Disabling full tests by default.

* Giving proper names, removing magic numbers and sanity checks of new
performance tests for the integral function.

* Giving proper names, making array static.
