035f133798 Add s390x architecture support 
This is a cumulative patch that adds the s390x LuaJIT implementation
by @ketank-new, @mundaym and @niravthakkar and others. It contains all
their contributions squashed together, plus minor stylistic cleanups.
It passes all the tests from LuaJIT-test-cleanup, except for
contents.lua, which fails on x86_64 as well.

dee73f516f Add s390x architecture support to DynASM 
s390x (IBM Z) is an architecture of server computers produced by IBM.
It is supported by a number of open source code generators, such as
GCC, LLVM, OpenJDK, eBPF, QEMU, Valgrind and Cranelift. One of the
missing pieces in the ecosystem support is LuaJIT.

The s390x support for LuaJIT was initially developed by @ketank-new,
@mundaym and @niravthakkar. It found its way into moonjit and luajit2
forks, as well as Fedora distro (as a patch). There were also smaller
contributions by @preetikhorjuvenkar, @Bisht13, @velemas,
@AlekseiNikiforovIBM, and @iii-i.

This is a cumulative patch of the DynASM changes from this work. It
contains all the contributions squashed together, plus minor stylistic
cleanups.
