target-i386: Introduce hw_{local,global}_breakpoint_enabled()
hw_breakpoint_enabled() returned a bit field indicating whether a local
breakpoint and/or global breakpoint was enabled. Avoid this number magic
by using explicit boolean helper functions hw_local_breakpoint_enabled()
and hw_global_breakpoint_enabled(), to aid readability.
Reuse them for the hw_breakpoint_enabled() implementation and change
its return type to bool.
While at it, fix Coding Style issues (missing braces).
