[PATCH v2 0/4] Support for arbitrary reggroups

[Stafford Horne <shorne@gmail.com>]

Traditionally registers have been limited to names like "vector",
"general", "system" which are hard coded in the gdbarch.  This patch allows
additional reggroups to be defined by the xml target description.

This is necessary for architectures like OpenRISC which have many
registers.

This series also adds documentation on tests for the feature of listing
register groups via the "info reg $reggroup" command.
