trivial: Simplify the spots that use TARGET_BIG_ENDIAN as a numeric value
TARGET_BIG_ENDIAN is *always* defined, either as 0 for little endian targets or as 1 for big endian targets. So we can use this as a value directly in places that need such a 0 or 1 for some reason, instead of taking a detour through an additional local variable or something similar.
