It turns out making the CFI check a release mode abort causes many,
if not the majority, of JITs to fail during unwinding as they do not
set up CFI sections for their generated code. As a result any JITs
that do nominally support unwinding (and catching) through their JIT
or assembly frames trip this abort.

[DA] refactor bounds inference in exactSIVtest and exactRDIVtest  (NFC) (#185719)

Replaces the `SmallVector`-based approach for computing the min/max of
affine domain bounds with `GetMaxOrMin` lambda returning `std::optional`
for better readability.
Previously, the code allocated a `SmallVector` to collect valid bounds
and relied on `smax(front(), back())` to handle the single-element case,
which may cause misunderstanding.

[LV] Simplify the chain traversal in `getScaledReductions()` (NFCI) (#184830)

I found the logic of this function quite hard to reason about. This
patch attempts to rectify this by splitting out matching an extended
reduction operand and traversing reduction chain.

- `matchExtendedReductionOperand()` contains all the logic to match an
  extended operand.
- `getScaledReductions()` validates each operation in the chain,
  starting backwards from the exit value, walking up through the operand
  that is not extended.
