[Ltrace-devel] [ltrace 21/21] x86_64/{trace.c, ptrace.h}: fix arguments handling

[Arnaud Patard]

- handle floats
- fix arguments in function return. regs may have changed and stack
  handling may (imho) become a nightmare so backup integer and fp regs
  at function/syscall entry with save_register_args
- As we're now getting regs in get_arch_dep, remove other ptrace()
  calls used to get registers
