 When given a containing face > 0, ST_AddIsoNode currently still check for
 containment in all faces rather than just the given one.

 Also, when given null or 0 containing face, ST_AddIsoNode makes a double
 scan: one only checking for MBR, and another checking the actual
 containment.

 Both cases can be optimized.

 The code I'm referring to entered the code base with r7222
