ptrace: arch_has_block_step
This defines the new macro arch_has_block_step() in linux/ptrace.h, a default for when asm/ptrace.h does not define it. This is the analog of arch_has_single_step() for step-until-branch on machines that have it. It declares the new user_enable_block_step function, which goes with the existing user_enable_single_step and user_disable_single_step. This is not used yet, but paves the way to harmonize on this interface for the arch-specific calls on all machines.
