  1. Guard unrecognized flags with if_not_msvc
  2. Add @dlfcn-win32 as a dep with if_msvc, removed the necessity of dlfcn on windows in triton-lang@323843c

@chsigg Could you please take a look?

- Add `BUILD` files.
- Remove `python/` folder.
- Disable short pointer.
- Fixup expensiveLoadOrStore().

There are two tests that failed under AddressSanitizer:

This is likely happening due to iterator being invalidated after
`alloc.erase()`.
This PR moves erases of allocations outside of a loop and fixes
heap-use-after-free issue.

Do you know if there is an easy way to run the tests under sanitizers
upstream? It would be handy if we can automate it, so we catch this kind
of errors early on.

When running
[convert_blocked1d_to_slice0](https://github.com/triton-lang/triton/blob/0ba5f0c3cd029d5c3d1f01b9bf29dac32c27345e/test/Conversion/tritongpu_to_llvm.mlir#L924)
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.
