[IR] Convert from nocapture to captures(none) (#123181)
This PR removes the old `nocapture` attribute, replacing it with the new
`captures` attribute introduced in #116990. This change is
intended to be essentially NFC, replacing existing uses of `nocapture`
with `captures(none)` without adding any new analysis capabilities.
Making use of non-`none` values is left for a followup.
Some notes:
* `nocapture` will be upgraded to `captures(none)` by the bitcode
reader.
* `nocapture` will also be upgraded by the textual IR reader. This is to
make it easier to use old IR files and somewhat reduce the test churn in
this PR.
* Helper APIs like `doesNotCapture()` will check for `captures(none)`.
* MLIR import will convert `captures(none)` into an `llvm.nocapture`
attribute. The representation in the LLVM IR dialect should be updated
separately.

[SCEV] Extend isImpliedCondOperandsViaRanges to independent predicates (#71110)
As far as I can tell, there's nothing in this code which actually
assumes the two predicates in (FoundLHS FoundPred FoundRHS) => (LHS Pred
RHS) are the same.
Noticed while investigating something else, this is purely an
oppurtunistic optimization while I'm looking at the code. Unfortunately,
this doesn't solve my original problem. :)

As usual, making it easier for an upcoming test delta to be seen.
Note that several of these are examples of extremely bad testing practice.
Checking internal debug output (for no real purpose), and checking the
result of a fully O2 + llc run instead of reducing the specific problematic

[IRCE] Enable decreasing loops of non-const bound
As a follow-up to r328480, this updates the logic for the decreasing
safety checks in a similar manner:
- CanBeMax is replaced by CannotBeMaxInLoop which queries
isLoopEntryGuardedByCond on the maximum value.
- SumCanReachMin is replaced by isSafeDecreasingBound which includes
some logic from parseLoopStructure and, again, has been updated to
use isLoopEntryGuardedByCond on the given bounds.

[IRCE] Enable increasing loops of variable bounds
CanBeMin is currently used which will report true for any unknown
values, but often a check is performed outside the loop which covers
this situation:
for (int i = 0; i < N; ++i)
...
if (N > 0)
for (int i = 0; i < N; ++i)
...
So I've add 'LoopGuardedAgainstMin' which reports whether N is
greater than the minimum value which then allows loop with a variable
loop count to be optimised. I've also moved the increasing bound
checking into its own function and replaced SumCanReachMax is another
isLoopEntryGuardedByCond function.
