Introduce a Loop::getLocStr stolen from LoopVectorize's static function getDebugLocString in order to have uniform debug output headers across LoopVectorize, LoopAccessAnalysis, and LoopDistribute. The motivation for this change is to have UpdateTestChecks recognize the headers and automatically generate CHECK lines for debug output, with minimal special-casing.
