Switch GetNodeBlock and GetTypeBlock to return an ArrayRef (#3220)

Browse Source 
This removes the risk of accidentally performing a vector copy when
calling these functions, and is a preparation step towards the new node
block allocation design.

This required changing how we build call expressions. Instead of
finishing the argument block and then later adding a return slot, we now
delay finishing the argument block and checking for conversions to
parameter types until after we've added the return slot to it.
