Convert PHI getIncomingValue() to foreach over incoming_values(). NFC.

Browse Source 
We already had a method to iterate over all the incoming values of a PHI.  This just changes all eligible code to use it.

Ineligible code included anything which cared about the index, or was also trying to get the i'th incoming BB.
