Update submodule lz4 #123

Closed wangyum closed 5 years ago

wangyum commented 6 years ago

LZ4 v1.8.2 is a performance focused release. For example, on a Mac OS-X laptop with an Intel Core i7-5557U CPU @ 3.10GHz, running lz4 -b silesia.tar compiled with default compiler llvm v9.1.0:

Version v1.8.1 v1.8.2 Improvement
Decompression speed 2490 MB/s 2770 MB/s +11%

Compression speeds also receive a welcomed boost, though improvement is not evenly distributed, with higher levels benefiting quite a lot more.

Version v1.8.1 v1.8.2 Improvement
lz4 -1 504 MB/s 516 MB/s +2%
lz4 -9 23.2 MB/s 25.6 MB/s +10%
lz4 -12 3.5 Mb/s 9.5 MB/s +170%

This pr update submodule lz4 to latest.

Can we release a new version depends on lz4 1.8.2?

Any reason not to merge this @odaira?
