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.

on functions and is confusing tools looking for data in text

In the adler32_neon function, during the last iteration of the
loop through "accum32_neon", we would load data after the end of the
buffer (in the ld1 instruction, the "start" register points to the end
of the buffer).
If this memory is unmapped, this would cause a segfault. If the memory
is mapped, the checksum would be correct because that value would
only be used in the next iteration, but this happens during the last
iteration.
To fix this, we can simply do the load before incrementing "start". And
while we're at it, we can load directly into d0_v/d1_v, saving a couple
of mov's.
Finally, the ld1 done during the function initialization can be removed
as the values aren't used for anything.

The goal of this patch is to make isa-l testsuite pass on s390 with
minimal changes to the library. The one and only reason isa-l does not
work on s390 at the moment is that s390 is big-endian, and isa-l
assumes little-endian at a lot of places.
There are two flavors of this: loading/storing integers from/to
memory, and overlapping structs. Loads/stores are already helpfully
wrapped by unaligned.h header, so replace the functions there with
endianness-aware variants. Solve struct member overlap by reversing
their order on big-endian.
Also, fix a couple of usages of uninitialized memory in the testsuite
(found with MemorySanitizer).
Fixes s390x part of #188.

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).

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
