Craig Topper e6b2495545 [SelectionDAG] Split SDNode::use_iterator into user_iterator and use_iterator. (#120531) ...

SDNode::use_iterator now returns an SDUse& when dereferenced.
SDNode::user_iterator returns SDNode*. SDNode::use_begin/use_end/uses
work on use_iterator. SDNode::user_begin/user_end/users work on
user_iterator.

We can now write range based for loops using SDUse& and SDNode::uses().
I've converted many of these in this patch. I didn't update loops that
have additional variables updated in their for statement.

Some loops use SDNode::use_iterator::getOperandNo() which also prevents
using range based for loops. I plan to move this into SDUse in a follow
up patch.
