Remove all slver legacy segments

The relic slver is no longer used for individual versioning
on functions and is confusing tools looking for data in text

its usefulness is waining. Fixes #221

Fix s390 build

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.

igzip: optimize convert_dist_to_dist_sym to branchless

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.
