s390: Document syntax to omit base register operand
Document the s390-specific assembler syntax introduced by commit
aacf780bca29 ("s390: Allow to explicitly omit base register operand in
assembly") to omit the base register operand B in D(X,B) and D(L,B) by
coding D(X,) and D(L,).
While at it document the alternative syntax to omit the index register
operand X in D(X,B) by coding D(,B) instead of D(B).
