thorpej 03efee5585 * Allow machine-dependent code to specify hooks for ptrace(2)
(__HAVE_PTRACE_MACHDEP) and procfs (__HAVE_PROCFS_MACHDEP).
  These changes will allow platforms like x86 (XMM) and PowerPC
  (AltiVec) to export extended register sets in a sane manner.

* Use __HAVE_PTRACE_MACHDEP to export x86 XMM registers (standard
  FP + SSE/SSE2) using PT_{GET,SET}XMMREGS (in the machdep
  ptrace request space).
* Use __HAVE_PROCFS_MACHDEP to export x86 XMM registers via
  /proc/N/xmmregs in procfs.
