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.

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.
