All callers updated.
(amd64_get_insn_details): Handle more 3-byte opcode insns.
(amd64_breakpoint_p): Delete.
(amd64_displaced_step_fixup): When fixing up after stepping an int3,

* i386-tdep.c: #include opcode/i386.h.
(i386_skip_prefixes): New function.
(i386_absolute_jmp_p): Constify argument.
(i386_absolute_call_p,i386_ret_p,i386_call_p,i386_syscall_p): Ditto.
