24bdb7576d Add debug options to Makefile.
We're going to need these for a while, so better to put in the
repository. Once we're happy things are working we can disable
the debug info and enable optimizations again.

2dcbf5be3e Implement more functions in the VM.
Also adds segmentation faults to stubbed out functions to make it
easier to work out what the control flow is.

ef3ff100f2 Fix decoding of REL_EXT.
REL_EXT has an argument which wasn't being properly jumped,
resulting in an early STOP (because the argument is 0).

361a298371 Add lhi instruction and fix immediate parsing.
We were reading immediate values as hexadecimal values, really we
want the default to be decimal unless the immediate has a '0x' prefix.

625aad5da0 Make LuaJIT compile on s390x.
I've disabled both the JIT and FFI for now. I've also stripped almost
all of the assembly out of vm_s390x.dasc, leaving only labels for the
most part. This is enough to get LuaJIT to compile but of course if
you try and run it it will explode.

The idea now is to re-add enough functionality to get a very basic
Lua program to run.

I've added a rough implementation of this code. It is untested but
does compile.

9b9e1ea667 Added SS-b mode
Currently I am not able to test the functionality of this mode, need some help in that.
Also for the time being I have created different function for parsing, we can merge that later, just to make sure SS-a doesnt break, I have not merged this since I was not able to test it.
Let me know your comments on this

106718249e Add support for SS-a instructions.
I've also changed the template parser so that it can handle suffixes
which are longer than 1 character. The suffix for SS-a instructions
is "SS-a". We could change this again later.

127f0fd745 Adding RRD support
Currently only "maer" is  implemented. I am not able to get this working, don't know if I am missing out something, or we need to add some more functionality for RRD.
