Instead of using a constant as default zlib header, create the header on the fly. Both zlib
header bytes depend on the wbits and compression level used.
Make sure that ISA-L compression level 0 is advertised as the fastest compression in
both the gzip header (setting xfl flag to 0x04) and the zlib header (as 0, fastest, other levels are 1, fast).

This removes the older linux builds and change the osx to
take the latest brew that comes with the image instead of
doing a brew update on every build.

This will make it easier for users to get the latest version. Installing with conda is easier than compiling it yourself. Distro packages (such as Debian's) do not always ship the latest version while conda-forge can. This badge will advertise this install method.

We should generate .note.gnu.property section with x86 assembly codes
for ELF outputs to mark Intel CET support when Intel CET is enabled
since all input files must be marked with Intel CET support in order
for linker to mark output with Intel CET support. Since nasm and yasm
can't generate the proper .note.gnu.property section, yasm-cet-filter.sh
and yasm-filter.sh are added to generate the proper .note.gnu.property
with linker help.

To support Intel CET, all indirect branch targets must start with
ENDBR32/ENDBR64. Here is a patch to define endbranch and add it to
function entries in x86 assembly codes which are indirect branch
targets as discovered by running testsuite on Intel CET machine and
visual inspection.

To reduce the cache missing events, the mix layout is changed
to PMULL+CRC. It also relaxes the final delay caused by data
dependency.
As results, the cold perf was improved about 20% and warm perf

called only once in program lifecycle. And HWCAP must
