[SelectionDAG] Fix AArch64 machine verifier bug when expanding LOOP_DEPENDENCE_MASK (#168221)

TargetConstant nodes don't match TableGen ImmLeaf patterns during
instruction selection. When this zero constant flows into the AArch64
CCMP formation code, the machine verifier hits an assertion in expensive
checks.

Fixes: #168227

[mlir][MemRef] Add UB as a dependent dialect and use `ub.poison` for Mem2Reg (#168066)

This patch adds `ub` as a dependent dialect to `memref`, and uses
`ub.poison` as the default value in `AllocaOp::getDefaultValue` for the
mem2reg pass.

This aligns the behavior of `mem2reg` with LLVM, where loading a value
before having a value should be poison.

[ADT] Make DenseMapBase::moveFrom safer (NFC) (#168180)

Without this patch, DenseMapBase::moveFrom() moves buckets and leaves
the moved-from object in a zombie state.  This patch teaches
moveFrom() to call kill() so that the move-from object is in a known
good state.  This brings moveFrom()'s behavior in line with standard
C++ move semantics.

kill() is implemented so that it takes the fast path in the destructor
-- both destroyAll() and deallocateBuckets().
