parisc: stop using task->ptrace for {single,block}step flags

task->ptrace flags belong to generic code, so instead thief some TIF_ bits to use. Somewhat risky conversion of code to test TASK_FLAGS instead of TASK_PTRACE in assembly, but it looks alright in the end.

parisc: split syscall_trace into two halves

Instead of fiddling with gr[20], restructure code to return whether or not to -ENOSYS. (Also do a bit of fiddling to let them take pt_regs directly instead of re-computing it.)

parisc: add missing TI_TASK macro in syscall.S

LDREG 0(%r1),%r1 really wants to be accessing thread_info.task, instead of hardcoding the 0.
