Switching to uload64 macro for better general solution.

In the newly added function isal_deflate_process_dict(), a null check
was added to the dictionary struct but was ineffectual because of the

Performance improvement for inflate to skip the time-consuming process of decode
table expansion when the header matches a known common dymanic one such as
produced by level 0 compression.

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
was improved about 4%.

The nmake default is changed for a modern nasm. Older nasm and yasm versions
will still work with windows but the nmake options must be changed appropriately
for max AS_FEATURE_LEVEL to match. Also now generates debug symbol pdb files.

This patch provides microarchitecture information
and make microarchitecture optimization possible. It
will trap into kernel due to mrs instruction. So it
should be called only in dispatcher, that will be
called only once in program lifecycle. And HWCAP must
be match,That will make sure there are no illegal
instruction errors.

Previously windows build could only use yasm because some procedural items such
as proc_start were not supported by nasm. This adds a few macros and fixes so
nasm can be used to build on windows.

The gf_{2-6}vect_dot_prod tests were kept in other_tests since the 5,6vect
functions were not strictly called by the higher level ec_encode_data() and
needed independent testing. As this has now changed the extra tests can be
removed as redundant.
