x86/32: Remove unused IA32_STACK_TOP and two externs

Browse source 
Since

  32974ad490 ("[IA64] Remove COMPAT_IA32 support")

IA32_STACK_TOP and ia32_setup_arg_pages() are not used anymore.

And

  675a081360 ("x86: unify mmap_{32|64}.c")

left behind ia32_pick_mmap_layout() extern declaration.

Remove them all.
