Add recordCount100Histogram() & recordSparseSlowlyHistogram() to RecordHistogram

Add recordCount100Histogram() & recordSparseSlowlyHistogram() to RecordHistogram

to RecordHistogram.

@param sample sample to be recorded, at least 1 and at most 99
Technically, values >99 will just fall into the overflow bucket, so this isn't a
