Ensure !NDEBUG with LLVM_ENABLE_ABI_BREAKING_CHECKS does not segfault (#113588)
In SelectionDAG, `TargetTransformInfo::hasBranchDivergence()` can be
called when both `NDEBUG` and `LLVM_ENABLE_ABI_BREAKING_CHECKS` are
enabled. In that case, the class member `TTI` is still initialized to
`nullptr`, causing a segfault.
Fix this by ensuring that all the calls to `hasBranchDivergence` and
`VerifyDAGDivergence` only occur when `NDEBUG` is disabled, and
`LLVM_ENABLE_ABI_BREAKING_CHECKS` is enabled.
