2022-05-13	bionic: Switch to jemalloc memory allocatorHEAD sugisawa-mr1	Danny Lin
	Overall, jemalloc performs significantly better than Scudo in Bionic's real-world memory_replay traces (all times in milliseconds): +----------------+-------+----------+ \| Trace \| Scudo \| jemalloc \| +----------------+-------+----------+ \| SQL \| 27 \| 21 \| \| Angry Birds 2 \| 2236 \| 1501 \| \| Camera \| 4251 \| 979 \| \| Candy Crush \| 2197 \| 1325 \| \| Gmail \| 594 \| 463 \| \| Maps \| 434 \| 344 \| \| Photos \| 1330 \| 477 \| \| PUBG \| 666 \| 416 \| \| surfaceflinger \| 221 \| 192 \| \| system_server \| 1921 \| 1416 \| \| SystemUI \| 102 \| 79 \| \| YouTube \| 363 \| 294 \| +----------------+-------+----------+ jemalloc also tends to use slightly less memory than Scudo for most traces. These tests were conducted on desktop x86 Linux with glibc and the latest stable version of each allocator, but they should still be relevant.
