Tested with strace.

[BZ #22433]
[BZ #22807]
* sysdeps/unix/sysv/linux/powerpc/sys/ptrace.h (__ptrace_request): Add
PTRACE_GETREGS, PTRACE_SETREGS, PTRACE_GETFPREGS, PTRACE_SETFPREGS,
PTRACE_GETVRREGS, PTRACE_SETVRREGS, PTRACE_GETEVRREGS,
PTRACE_SETEVRREGS, PTRACE_GETREGS64, PTRACE_SETREGS64,
PTRACE_GET_DEBUGREG, PTRACE_SET_DEBUGREG, PTRACE_GETVSRREGS,
PTRACE_SETVSRREGS, and PTRACE_SINGLEBLOCK.
---
 v2:
 - added PTRACE_SINGLEBLOCK;
 - fixed comments about PTRACE_GETVSRREGS and PT_SETVSRREGS;
 - removed the note about conflict between <asm/ptrace.h> and <sys/ptrace.h>
   that is going to be fixed by "powerpc: Undefine Linux ptrace macros
   that conflict with __ptrace_request" fix.
