Adds compile time flag -mllvm -memprof-histogram and runtime flag histogram=true|false to turn Histogram collection on and off. The -memprof-histogram flag relies on -memprof-use-callbacks=true to work. Updates shadow mapping logic in histogram mode from having one 8 byte counter for 64 bytes, to 1 byte for 8 bytes, capped at 255. Only supports this granularity as of now. Updates the RawMemprofReader and serializing MemoryInfoBlocks to binary format, including changing to a new version of the raw binary format from version 3 to version 4. Updates creating MemoryInfoBlocks with and without Histograms. When two MemoryInfoBlocks are merged, AccessCounts are summed up and the shorter Histogram is removed. Adds a memprof_histogram test case. Initial commit for adding AccessCountHistograms up until RawProfile for memprof
