7a49be07be Added the required character for encoding 
I have added the number depending on the number of operands, pls check for the ones which access memory.
Also For base register and displacement, should I assume that it will be passed in the same order as it is expected, since I dont have any means to see the output, I am confused a bit for those add modes.
Since we decided to test RR first, thats in progress, but would like to add others as well.

538a4afee2 Updated size of the instruction word 
We can discuss if we need to keep it 6 bytes or 8 bytes long, Not clear enough to me as well

203006579f Removed the extra check in parse_reg 
The extra check for register is currently ignored, and trying to see what value does the encode function return. Its still to be worked out, how this value is used later, after decoding.

3288e547bf Update vm_s390x.dasc 
added definations to macros to test operand type refeered x86 definations
no JUMP instruction found for s390x used BRANCH RELATIVE on CONDITION instead (brc)
Not sure how the condition will be checked , need to discuss this

'????' has to be replaced with s390x complement instruction

5887962b0e Add assembly for decoding instructions. 
Still guessing at this point. This code will need to be changed.

dbf789536c Fix stack frame layout. 
f8-f15 are callee-saved (not f0,f2,f4 and f6). There isn't space
for them in the caller's stack frame so we need to increase the
size of the interpreter's stack frame.

5a69b4638a Fixup the save/restore register macros. 
I believe these macros obey the C calling convention, so we need to
allocate our stack frame and save all callee-save registers. We
can tune it later if it turns out we don't need all the registers.

d50f8aa92b Add preliminary frame offsets. 
These are educated guesses at this point. We might need more stack space because
we don't have many free registers available.

e577db52c5 Increase range of GG_State loads via IR_FLOAD with REF_NIL. 
Require 32 bit alignment and store offset/4 instead.
Otherwise this can overflow the 10 bit limit for the FOLD op2 key.
