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).
