[PATCH] D49114: Add a clang-tidy check for "magic numbers"

Perhaps M_PI wasn't the best example, as its value won't change soon, but other numbers should be defined in relation to constants.

Also I have seen coding guidelines suggesting "100" is grandfathered due to 100% calculations. 2 and 10 due to logarithms, etc. Not sure where to draw the line there.
