compress: add benchmark-style test
This is useful to test the behaviour of the compressor for various buffer sizes. Time is limited to a minute per compression, since otherwise, when LZ4 takes more than a second which is necessary to reduce the noise, XZ takes more than 10 minutes. % build/test-compress-benchmark (without time limit) XZ: compressed & decompressed 2535300963 bytes in 794.57s (3.04MiB/s), mean compresion 99.95%, skipped 3570 bytes LZ4: compressed & decompressed 2535303543 bytes in 1.56s (1550.07MiB/s), mean compresion 99.60%, skipped 990 bytes % build/test-compress-benchmark (with time limit) XZ: compressed & decompressed 174321481 bytes in 60.02s (2.77MiB/s), mean compresion 99.76%, skipped 3570 bytes LZ4: compressed & decompressed 2535303543 bytes in 1.63s (1480.83MiB/s), mean compresion 99.60%, skipped 990 bytes It appears that there's a bug in lzma_end where it leaks 32 bytes.
