Move SDNode::IROrder in to padding to save space. NFC.

Browse Source 
There was a 32-bit padding gap between 'unsigned short NumOperands, NumValues;' and 'DebugLoc debugLoc.  Move 'unsigned IROrder' in to that gap.

This trims the size of SDNode's from 76 bytes (really 80 due to alignment) to 72 bytes.
