[PATCH 09/14] gdb/testsuite: Fix break-always.exp for enabled do_reload_on_run

[Shahab Vahedi]

From: Anton Kolesov <Anton.Kolesov@synopsys.com>

GDB testsuite proc "runto" is not compatible with "always-inserted on"
when gdb,do_reload_on_run is set - in this case "runto" will insert
breakpoint, and then will do a reload, which will overwrite an already
inserted breakpoint, so further continue will not succeed. There is no
problem with "always-inserted off", because breakpoints are inserted
automatically by GDB before resuming, so reloading doesn't overwrite
them.

gdb/testsuite/ChangeLog:
2016-07-19  Anton Kolesov <Anton.Kolesov@synopsys.com>

	* gdb.base/break-always.exp: Move "runto" before
	"always-inserted on".
