[ConstantFolding] Non-constrained functions in strictfp

Non-constrained function calls, allowed in strictfp functions by
PR188297, are equivalent to their constrained counterparts with dynamic
rounding and strict exception handling. When constant folding the calls
of these functions, some cases cannot be folded due to unknown rounding
mode or floting-point exceptions that can be lost. This change adapts
constant folding for these case.

[IR] Use iteration limit in stripPointerCastsAndOffsets (#190472)

Using a SmallPtrSet is not quite free for such a frequently called
operation. However, calls on ill-formed IR are not particularly rare, so
some iteration limit is needed. Therefore, use a simple counter.

Termination statistics on a Clang Release build for N>5:

   2448 N=6
   1295 N=7
    480 N=8
    294 N=9
    160 N=10
  14350 (endless loop)

Therefore, bound the number of iterations by 12, which should cover most
practically relevant cases.

It is worth noting that _all_ of the endless loop cases have the

[SCEV] Move NoWrapFlags definition outside SCEV scope, use for SCEVUse. (#190199)

The patch moves out of SCEV's scope so they can be re-used for SCEVUse.
SCEVUse gets an additional getNoWrapFlags helper that returns the union
of the expressions SCEV flags and the use-specific flags.

SCEVExpander has been updated to use this new helper.

In order to avoid other changes, the original names are exposed via
constexpr in SCEV. Not sure if there's a nicer way. One alternative
would be to define the enum in struct, and have SCEV inherit from it.

The patch also clarifies that the SCEVUse flags encode NUW/NSW, and
hides getInt, setInt, etc to avoid potential mis-use.

DiagnosticInfo: Fix stack-use-after-scope in DiagnosticInfoStackSize (#190442)

The string literal "stack frame size" passed to the base class
constructor created a temporary Twine that was destroyed after
the base constructor completed, leaving a dangling reference.

Fix by storing the Twine as a member variable in the derived class,
ensuring it lives as long as the diagnostic object itself.

[lldb] Fix alias parsing with joined options (#190301)

Fixes a crash with the following alias, which I use for printing the
contents of pointer variables:

```
command alias vp v -P1
```

At some point in the recent-ish past, parsing this alias has started
crashing lldb. The problem is code that assumes the option and its value
are separate. This assumption causes an index past the end of a vector.

This fix changes `FindArgumentIndexForOption`. The function now returns
a pair of indexes, the first index is the option, the second index is
the index of the value. In the case of joined options like `-P1`, the
two indexes are the same.

To avoid potential memory leaks, this PR defers the ModuleOp cloning
until after the verification check. If the check fails, the
moduleVariant might not be properly deallocated(original
implementation), leading to a memory leak. Therefore, this PR ensures
that the clone operation is only performed after a successful check. It
is part of https://github.com/llvm/llvm-project/pull/189353.

[Polly] Assumptions used to derive domain must not be pruned by that domain (#190436)

The code that emits the conditions for whether a statement is executed
by checking whether we are in the statement's domain may apply
assumptions (such as an integer truncation being reversible). Later code
then assumes that these assumptions are only relevent for then the
statement is executed, but actually it is used for determining whether
it is executed.

Break this circular reasoning by introducing an `IsInsideDomain` flag
that can be set when the domain has not been verified yet.

[DSE] Introduce `eliminateRedundantStoresViaDominatingConditions` (#181709)

While optimizing tautological assignments, if there exists a dominating
condition that implies the value being stored in a pointer, and such a
condition appears in a node that dominates the store via equality edge,
then subsequent stores may be redundant, if no write occurs in between.
This is achieved via a DFS top-down walk of the dom-tree, collecting
dominating conditions and propagating them to each subtree, popping them
upon backtracking.

This also generalizes `dominatingConditionImpliesValue` transform, which
was previously taking into account only the immediate dominator.
