x86emul: relax asm() constraints

Let's give the compiler as much liberty at picking instruction operands
as possible. Also drop unnecessary size modifiers when the correct size
can already be derived from the asm() operands. Finally also drop an
"unsigned" from idiv_dbl()'s second parameter, allowing a cast to be
eliminated.
