Introduce tests to cover simple scenarios where user is watching memory which can be accessed by kernel as well. We also support _MODE_EXACT with _SETHWDEBUG interface. Move those testcases outside of _BP_RANGE condition. This will help to test _MODE_EXACT scenarios when CONFIG_HAVE_HW_BREAKPOINT is not set, eg: $ ./ptrace-hwbreak ...
