Until we have sparse histograms, to track error codes, we are using
UMA_HISTOGRAM_ENUMERATION and specify 16000 as the bucket size. Bumped up kBucketCount_MAX to 2**16. BUG=74618 TEST=We need to test MemoryMappedFile on windows in the browser to send histogram data for MemoryMappedFile.CreateFileMapping.
