Fix bug in 64 bit codegen causing us to always go slowcase in apply.

After introducing the direct instruction pointer in functions the
CallApplyLazy method was changed on all platforms. The change made to
the 64 bit version was wrong, not using the right operand for the code
comparisons always forcing us into slow case.
