Hardware watchpoints turned off, inferior not yet started.
https://sourceware.org/ml/gdb-patches/2013-10/msg00477.html
gdb/ChangeLog
* breakpoint.c (update_watchpoint): If hardware watchpoints are
forced off, downgrade them to software watchpoints if possible,
and error out if not possible.
(watch_command_1): Move watchpoint type selection closer to
watchpoint creation, and extend the comments.
gdb/testsuite/ChangeLog
* gdb.base/watchpoints.exp: Add test for setting software
watchpoints of different types before starting the inferior.
