user facing message literal strings as found using codespell. Fix
these.

The cold versions of tests depended on a fixed size of last level
cache that is too low on some arch and too high for the total
available memory on others.

The relic slver is no longer used for individual versioning
on functions and is confusing tools looking for data in text
sections. This removes all instances instead of fixing since
its usefulness is waining. Fixes#221

The file types.h has long been misnamed and overlaps with
functionality in the test helper routines.

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.
Verified with
$ CC="gcc -Wl,-z,cet-report=error -fcf-protection" CXX="g++ -Wl,-z,cet-report=error -fcf-protection" .../configure x86_64-linux
$ make -j8
$ make -j8 check
with both nasm and yasm on both CET and non-CET machines.

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.

Some CPUs report "illegal instruction" error for the crc test because
they do not support the relevant optional feature . This can be fixed by
introducing CPU feature detection for AArch64 .
The difference with the x86 implementation is the dispatcher . It is based
on the glibc function `getauxval(AT_HWCAP)` and `getauxval(AT_HWCAP2)` , not
registers or instructions .
On a heterogeneous system (big.LITTLE) , it is dangerous to detect CPU
features using identification registers . And while it is possible to use
architectural feature registers from userspace on recent kernels, this
won't necessarily work with older platforms . Thus we use the HW_CAPs
exported from the kernel (and visible in getauxval) as the solution.
- According to kernel suggestion , getauxval should be used for this purpose .

- According to AAPCS result/paramter registers should be saved/restore for function call

If an application treats these functions as function pointers, and this
lib (isa-l) is compiled into solib, a segmentation fault may occur.
For example: Ubuntu 16.04 on arm64 platfrom will be crash, because the
linker does not know that this symbol is a function, so mark the function
type explicitly with %function to solves this issue.
