[test] Fix playTests.sh with space in binary path

Nick Terrell c7ae28a67d [circleci] Run test-license.py 
Run it first because it is very fast (~1 second)

Nick Terrell ef9e6fe227 [test] Fix playTests.sh with space in binary path 
playTests.sh didn't work when `ZSTD_BIN` or `DATAGEN_BIN` had a space in
the path name. This happens for me because I split the cmake build
directory by compiler name, like "Clang 9.0.0".

The fix is to replace all instances of `$ZSTD` with the `zstd()`
function, and the replace `$DATAGEN` with `datagen()`. This will allow
us to change how we call zstd/datagen in the future without having to
change every callsite.

Nick Terrell 1f144351b7 [test] Add a test that checks for valid copyright and licenses 
Tests all `.h`, `.c`, `.py`, and `Makefile` files for valid copyright
and license lines. Excludes a small number of exceptions (threading, and
divsufsort).

* Copyright does not contains `present`
* Copyright contains `Facebook, Inc`
* Copyright contains the current year
* License contains exactly the lines we expect

Nick Terrell ac58c8d720 Fix copyright and license lines 
* All copyright lines now have -2020 instead of -present
* All copyright lines include "Facebook, Inc"
* All licenses are now standardized

The copyright in `threading.{h,c}` is not changed because it comes from
zstdmt.

The copyright and license of `divsufsort.{h,c}` is not changed.

Align decompress sequences loop to 32+16 bytes
 2020-03-24 11:42:59 -07:00
Nick Terrell 8d0ee37ac0 Align decompress sequences loop to 32+16 bytes 
The alignment is added before the loop, so this shouldn't hurt
performance in any case. The only way it hurts is if there is already
performance instability, and we force it to be stable but in the bad
case.

This consistently gets us into the good case with gcc-{7,8,9} on an
Intel i9-9900K and clang-9. gcc-5 is 5% worse than its best case but has
stable performance. We get consistently good behavior on my Macbook Pro
compiled with both clang and gcc-8. It ends up in the 50% from DSB and
50% from MITE case, but the performance is the same as the 85% DSB case,
so thats fine.
