cmd/asm, cmd/internal/obj/s390x: add new s390x instructions for SSA
This commit adds the following instructions to support the new SSA
backend for s390x:
32-bit operations:
ADDW
SUBW
NEGW
FNEGS
Conditional moves:
MOVDEQ
MOVDGE
MOVDGT
MOVDLE
MOVDLT
MOVDNE
Unordered branches (for floating point comparisons):
BLEU
BLTU
Modulo operations:
MODW
MODWU
MODD
MODDU
The modulo operations might be removed in a future commit because
I'd like to change DIV to produce a tuple once the old backend is
removed.
This commit also removes uses of REGZERO from the assembler. They
aren't necessary and R0 will be used as a GPR by SSA.
