sys/contrib/zstd: Import zstd 1.4.8

2020-12-25T15:42:41+00:00

Merge commit 'f6ae97673c28bdb9ae795bd235ab6f26f2536a2d' into main

Changes from 1.4.5:
  * https://github.com/facebook/zstd/releases/tag/v1.4.8
  * https://github.com/facebook/zstd/releases/tag/v1.4.7
  (and there was no public v1.4.6)

Conflicts:
	sys/contrib/zstd/lib/common/zstd_internal.h (new ZSTD_NO_INTRINSICS)

Update to Zstandard 1.4.5

2020-05-23T21:23:46+00:00

As usual, the full release notes are found on Github:

  https://github.com/facebook/zstd/releases/tag/v1.4.5

Notable changes include:

* Improved decompress performance on amd64 and arm (5-10%
  and 15-50%, respectively).
* '--patch-from' zstd(1) CLI option, which provides something like a very fast
  version of bspatch(1) with slightly worse compression.  See release notes.

In this update, I dropped the 3-year old -O0 workaround for an LLVM ARM bug;
the bug was fixed in LLVM SVN in 2017, but we didn't remove this workaround
from our tree until now.

Update to Zstandard 1.3.8

2018-12-29T21:18:01+00:00

This merge brings in a couple new files, which needed to be attached to the
build; a new dependency on , which must be stubbed; and a name
change in the Context parameter constants, from ZSTD_p_foo to ZSTD_c_foo.

Significantly, it fixes a kernel build error with GCC where floating-point
functions were included in the kernel build, by hiding them under the same
compile-time #ifdef that already covered their invocation.  That issue was
introduced to FreeBSD in the 1.3.7 update and tracked upstream here:

  https://github.com/facebook/zstd/issues/1386

The full 1.3.8 release notes can be found on Github:

Update to Zstandard 1.3.4

2018-03-26T23:54:59+00:00

Includes our local patch to conditionalize use of __builtin_clz(ll) on
Clang's __has_builtin() (which is just defined to false when building with
GCC).

The issue is tracked upstream at https://github.com/facebook/zstd/pull/884 .
Otherwise, these are vanilla Zstandard 1.3.4 files.
