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.

Issue with reading header only appears when combined with new feature in cli of
multiple concatenated gzip files.

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.

Fixes invalid logic that attempted to eliminate unnecessary copy of input to the
history buffer in cases where it is not required. Correction should improve
performance and not change functionality.

convert_dist_to_dist_sym uses long if/else branch to get look back distance.
The distance calculation is well formed for each distance range, so it could
be optimized for a branchless version.

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);
