This commit updates payloadtool with a tracking allocator, showing: * total allocations * total deallocations * total bytes allocated * peak bytes live This information is exposed on stderr if `--memory-stats` is provided to payloadtool. The goal is to enable more convenient optimization flows for lading developers. Signed-off-by: Brian L. Troutwine <[email protected]>
