Implement "to_stopped_by_hw_breakpoint" for x86 debug registers.
Report that a thread is stopped by a hardware breakpoint if a non-data
watchpoint is set in DR6. This change should be a no-op since a target
still needs to implement the "to_supports_stopped_by_hw_breakpoint"
method before this function is used.
gdb/ChangeLog:
* nat/x86-dregs.c (x86_dr_stopped_by_hw_breakpoint): New function.
* nat/x86-dregs.h (x86_dr_stopped_by_hw_breakpoint): New
prototype.
* x86-nat.c (x86_stopped_by_hw_breakpoint): New function.
(x86_use_watchpoints): Set "stopped_by_hw_breakpoint" target
method.
