Roman Lebedev a4e3b50e26 [DAGCombiner][X86][AArch64] (x - C) + y -> (x + y) - C fold. Try 2 
Summary:
Only vector tests are being affected here,
since subtraction by scalar constant is rewritten
as addition by negated constant.

No surprising test changes.

This is a recommit, originally committed in rL361852, but reverted
to investigate test-suite compile-time hangs.
