Separate out ANSI-standard signals
This commit reorders various pieces of code to separate ANSI-standard
signals from other signals that need checking. Comments are added to
document this, and to document the ordering of the signals.

2014-06-09 Gary Benson <gbenson@redhat.com>
* common/signals.c (gdb_signal_from_host): Reorder to separate
the always-available ANSI-standard signals from the signals that
require checking.
(do_gdb_signal_to_host): Likewise.
* proc-events.c (signal_table): Likewise.

* gdb.base/sigall.c [Functions to send signals]: Reorder to
separate the always-available ANSI-standard signals from the
signals that require checking.
(main): Likewise.
* gdb.reverse/sigall-reverse.c [Functions to send signals]:
Likewise.
(main): Likewise.
