Um... Then why are we bothering with all these BE checks? Just so in the future when/if node runs on BE we're ready for it?

And I'm not disagreeing with you about `__BYTE_ORDER`.  Just that it will give more consistent results with v8. It is used in several important places, for example: `HeapNumberToBoolean` which is used in `ToBoolean`; `kConstructionCountOffset` which is used in `construction_count` which is used in `DetachInitialMap` which is used to GC.

Guess I'm saying that if v8 doesn't properly detect BE, but then node does, I'd consider the result to be inconsistent.
