new helper: current_pt_regs()
Normally (and that's the default) it's just task_pt_regs(current). However, if an architecture can optimize that, it can do so by making a macro of its own available from asm/ptrace.h. More importantly, some architectures have task_pt_regs() working only for traced tasks blocked on signal delivery. current_pt_regs() needs to work for *all* processes, so before those architectures start using stuff relying on current_pt_regs() they'll need a properly working variant.
