Simon Pilgrim cd297b5b93 [DAGCombine] Add ADD(SUB,SUB) combines
Noticed while investigating PR40483, and fixes the basic test case from the bug - but not a more general case.

We're pretty weak at dealing with ADD/SUB combines compared to the SimplifyAssociativeOrCommutative/SimplifyUsingDistributiveLaws abilities that InstCombine can manage.
