Update documentation for ARM architecture

2016-06-09  Stefan Bruens  <stefan.bruens@rwth-aachen.de>

	* doc/invoke.texi (ARM Options): Use lexicographical ordering.
	Correct usage of @samp vs @option, add @samp where appropriate.
	Add -march={armv6k,armv6z,arm6zk}, remove -march=ep9312.
	Add armv6s-m and document it, as it is no official ARM name.
