Dead code removal, mostly; the only exception is a bit of cleanups
on itanic (getting rid of redundant stack unwinds - each access_uarea()
call does it and we call that 7 times in a row in ptrace_[sg]etregs(), *after*
having done it ourselves in the caller; location where the user registers
have been spilled won't change under us, and we can bloody well just call
access_elf_reg() directly, giving it the unw_frame_info we'd calculated for
our own purposes).

[ia64] missed cleanups from switch to regset coredumps
[ia64] ptrace_[sg]etregs(): use access_elf_reg() instead of access_uarea()
