Optimize code placement in loop to eliminate unconditional branches or move unconditional branch to the outside of the loop. e.g.
...
/// A:
/// ...
/// <fallthrough to B>
///
/// B: --> loop header
/// ...
/// jcc <cond> C, [exit]
///
/// C:
/// ...
/// jmp B
///
/// ==>
///
/// A:
/// ...
/// jmp B
///
/// C: --> new loop header
/// ...
/// <fallthough to B>
///
/// B:
/// ...
/// jcc <cond> C, [exit]

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.)
