4992196322 Fix PR4152: asm constraint validation happens before dag combine, so we 
need to work a bit to combine things like (x+c1+c2) into x+c3.

43e91b9c2f Use X86AddrNumOperands instead of magic constant one 
more place.  This fixes a bunch of x86-64 JIT regressions.
(Introduced when the value of the magic constant changed
in 68645.  At the time apparently nobody noticed; failures
were hidden in 70343-70439 by an unrelated bug, so showed
up again as "new" failures in 70440.)
