IA32: model integer division and modulus closer to the machine
lib/Integers.v: define division-remainder of a double word by a word
ia32/Asm.v: use it to give Pdiv and Pidiv their "true" semantics like in the processor; add Pcltd as an instruction
ia32/*: adapt accordingly
Additional benefit: Pcltd could be used for an alternate implementation of shrximm.
