[Matrix] Only run matrix lowering early with -O0. Currently matrix lowering is run twice if OptLevel > 0. Fix that and also add a test for OptLevel > 0 with matrix lowering enabled.

[MemCpyOptimizer] Change required analysis order for BasicAA/PhiValuesAnalysis This is a followup to 1ccfb52a61748, which made a number of changes including the apparently innocuous reordering of required passes in MemCpyOptimizer. This however altered the creation order of BasicAA vs Phi Values analysis, meaning BasicAA did not pick up PhiValues as a cached result. Instead if we require MemoryDependence first it will require PhiValuesAnalysis allowing BasicAA to use it for better results. I don't claim this is an excellent design, but it fixes a nasty little regressions where a query later in JumpThreading was getting worse results.

[DSE] Switch to MemorySSA-backed DSE by default. The tests have been updated and I plan to move them from the MSSA directory up. Some end-to-end tests needed small adjustments. One difference to the legacy DSE is that legacy DSE also deletes trivially dead instructions that are unrelated to memory operations. Because MemorySSA-backed DSE just walks the MemorySSA, we only visit/check memory instructions. But removing unrelated dead instructions is not really DSE's job and other passes will clean up. One noteworthy change is in llvm/test/Transforms/Coroutines/ArgAddr.ll, but I think this comes down to legacy DSE not handling instructions that may throw correctly in that case. To cover this with MemorySSA-backed DSE, we need an update to llvm.coro.begin to treat it's return value to belong to the same underlying object as the passed pointer. There are some minor cases MemorySSA-backed DSE currently misses, e.g. related to atomic operations, but I think those can be implemented after the switch. This has been discussed on llvm-dev: http://lists.llvm.org/pipermail/llvm-dev/2020-August/144417.html For the MultiSource/SPEC2000/SPEC2006 the number of eliminated stores goes from ~17500 (legayc DSE) to ~26300 (MemorySSA-backed). More numbers and details in the thread on llvm-dev.
