Add support for extensions in the .machine pseudoop on S/390, e.g. ".machine zEC12+nohtm+vx"
gas * doc/c-s390.texi: Add documentation.
Add missing code markup.
* config/tc-s390.c (current_flags): New static variable.
(s390_parse_cpu): Parse cpu flags a la "+nohtm" etc.
(s390_setup_opcodes): Use cpu flags to determine the set of opcodes.
Fix indentation.
(md_parse_option): Call s390_parse_cpu with the new signature.
(s390_machine): Likewise.
Keep track of current_flags.
Simplify code a bit.
