[PATCH] D127115: [RFC][DAGCombine] Make sure combined nodes are added back to the worklist in topological order.

[Jay Foad via Phabricator via llvm-commits]

FYI I ran this patch on an internal corpus of AMDGPU graphics shaders and didn't see anything alarming. There was a slight change in the way fmul+fadd are combined into fma, but I don't think it was consistently worse - just different. Anyway I will work on that, but I do not think it should block this patch.
