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

Build with Makefile.unx on unsupported CPUs fail . It reports
"undefine references". Fix it with adding base aliases files
into sources list

Also test the assembler for modern instruction support and set appropriate
defines.

This patch addresses one build failure and fixes several build warnings
for Arm (some for x86 too).
- Fix dynamic relocation link failure of ld.bfd 2.30 on Arm
[log] relocation R_AARCH64_ADR_PREL_PG_HI21 against symbol `xor_gen_neon' which may bind externally can not be used when making a shared object
- Add arch dependent "other_tests" to exclude x86 specific tests on Arm
[log] isa-l/erasure_code/gf_2vect_dot_prod_sse_test.c:181: undefined reference to `gf_2vect_dot_prod_sse'
- Check "fread" return value to fix gcc warnings on Arm and x86
[log] warning: ignoring return value of ‘fread’, declared with attribute warn_unused_result [-Wunused-result]
fread(in_buf, 1, in_size, in_file);
^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
- Fix issue of comparing "char" with "int" on Arm. "char" is unsigned
on Arm by default, an unsigned char will never equal to EOF(-1).
[Log] programs/igzip_cli.c:318:31: warning: comparison is always true due to limited range of data type [-Wtype-limits]
while (tmp != '\n' && tmp != EOF)
^~
- Include <stdlib.h> to several files to fix build warnings on Arm
[log] igzip/igzip_inflate_perf.c:339:5: warning: incompatible implicit declaration of built-in function ‘exit’
exit(0);

Moved the afl fuzz test and added llvm fuzz tests including inflate
and round trip compress and inflate. Currently only works with clang,
std makefile and libFuzzer installed. Need to add checking and
support later when libfuzzer is more tightly integrated into the
compiler.

The traditional makefile was failing on install. Changes to build isa-l.h in
the same way that automake does it.

Makefile.am was missing make checks and Makefile.unx was missing make check.
Added both to be consistent with nmake file.
