1. Rewrite code generation of insert_slice_async.
2. Correct the wrong index passed to extract_slice in pipeline.
3. Add a prologue in pipeline to wait for dangling cp.asyncs.
4. Move scf to cf conversion inside TritonGPUToLLVM because we need to
perform membar before scf to cf. It shouldn't be a technical limitation
and could be improved by a more general membar analysis.
5. Use an attribute to memoize the shared memory size and support
dynamic shared memory.
6. Prevent the combine pass to reorder insert_slice and extract_slice
across async_wait

This PR helps to
1. Adapt the existing DotOp conversion to the design of the new
DotOperand layout,
2. Making the DotOp conversion work with both shared-layout inputs case
and dotoperand-layout inputs case for further upstream switch.
This PR does the following:
- CUDA utilities (e.g., cuGetInfo) won't be compiled as part of libtriton.so anymore.
- Refactoring driver/llvm.cc to split it between PTX codegen and python.
- By extension this will also deprecate include/external so Triton won't have to live with a copy of some CUDA/Hip headers anymore.
- `triton-translate` becomes a `triton.tools.aot` Python utility that re-uses functions from the triton.compile sub-module.
LLVM Conversion for Dot op.
Due to the lack of `convert_layout`, currently, the dot only supports
the following combination of operands
- `$a` in shared layout
- `$b` in shared layout
- `$c` in MMA layout(but only Splat-like, leaving the generic cases to
`convert_layout`)
This PR focus on `mma.16816` related logic support, leaving the other
cases to the following PR.

This code in this branch assumes the `src` operand in
`insert_slice_async` always aliases the result, which shouldn't hold for
generally cases but is just a workaround to make the pipeline pass work.
I'm also working on the complete analysis in another
[branch](https://github.com/openai/triton-mlir/tree/keren/analyze-slice).
This PR does
1. Add some C++ tests for `PTXFormat`
2. Enhance the functionality of `PTXFormat`, make a `PTXInstr` instance
can be called multiple times similar as a C function.
This PR does the following things:
- Code refactoring on Load and Store op codegen, rewrite with same logic
and share much code
- Support the vectorized load/store
This PR both simplifies the layout conversion simplification algorithm, and also improves it to make it work with vectorized element-wise ops. The conversion optimizer still has a lot of room for improvements, and other PRs will address its limitations (ideally via some sort of explicit cost model)
This deprecates the use of release-build LLVM hosted by the LLVM project, which makes debugging harder for developers.
This PR implements the following solution:
1. Create LLVM release tarballs with assert enabled on our own (using Docker)
2. Host them in our own GitHub repositories
3. Use our LLVM for CI and/or development if `TRITON_USE_ASSERT_ENABLED_LLVM=1` is set.
The purpose of this PR is analyzing shared memory aliases so that we can
fix memory allocation bugs and save memory allocations in triton code
involving complex control flows.
Changes to memory bar and allocation are on the way.
