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.
MFC after: I won't, but feel free

This merge brings in a couple new files, which needed to be attached to the
build; a new dependency on <limits.h>, 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
