  Reorder, reword, and complete the s390-specific option descriptions.
Align the formatting of s390-specific assembler options to that of the
general assembler options in "as --help".

While at it change a warning message to use the term "z/Architecture"
instead of the deprecated "esame" (ESA Modal Extensions or ESAME) one.
