[Bug translator/2634] New: printf incorrectly pushes arguments to %p formats on i686

["joshua dot i dot stone at intel dot com" <sourceware-bugzilla at sourceware dot org>]

$ stap -e 'probe begin{ printf("%p %d\n",-1,0) exit() }'
ffffffff 4294967295

It is apparant that -1 is being pushed on the stack as a 64-bit value, and then
the printf internals are pulling off only 32-bits for a pointer.  Thus when it
gets to the %d it is at the wrong position on the stack.

The translator needs to cast the -1 down to the pointer size in the call to
_stp_printf / _stp_sprintf.
