Should F8E4M3FNUZ really need to be removed?

Also below, in some places F8E4M3FN got added, in other places F8E4M3FNUZ is being replaced. It would be good to explain what we want in the PR description and apply it consistently. Or maybe I'm missing something and this is all intentional?

F8E4M3FNUZ needs to be listed here, as we want likely want support for it on other platforms (although I haven't tested this).

In places where it is NVIDIA PTX targetted, we replace F8E4M3FNUZ with F8E4M3FN, and in other "generic" places we add F8E4M3FN

Triton ends up computing a rank of a matrix with 0 columns during linear
layout lowering, which trips up f2reduce, and causes undefined behavior,
detectable through
[UBSAN](https://clang.llvm.org/docs/UndefinedBehaviorSanitizer.html).

Fix this by returning the rank (0) early in these cases, without calling
f2reduce.

The problem seems to be that we are iterating through uses, and then
removing some of them inside the loop, which invalidates the iterator.

…leaveTMem.cpp (triton-lang#7924)

`TritonNvidiaGPU/interleave_tmem.mlir` fails under address sanitizer. 

The `ConstantIntOp` operations were created without attachment to any
block in https://github.com/triton-lang/triton/pull/7622, which caused a
memory leak. This change addresses the problem by adding an insertion
point.

…mlir` test

IIUC, the initialization order between static and non-static variables is not guaranteed, so we can't use the previous non-static variable to initialize a static one later on. Working around that by moving it into a static function member.

We discovered this when upgrading to a newer LLVM version, so it might only be reproducible with new LLVM.

Here is the error:
