* runtime/uprobes/uprobes.[ch], uprobes_i386.[ch],
uprobes_ppc64.h, uprobes_s390.h: Adjusted SLOT_IP and
arch_validate_probed_insn to accept task pointer (needed by
x86_64); added uprobe_probept_arch_info and uprobe_task_arch_info
(ditto).
* runtime/uprobes/uprobes_i386.c: Fixed a couple of glitches
discovered when porting to x86_64
