9f75defd57 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
sections. This removes all instances instead of fixing since
its usefulness is waining. Fixes #221

d3cfb2fb77 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.
