998fd5f9af [FRONTEND] Make triton.compile work without a cuda context (#708)
This allows compiling in a subprocess. I'm not seeing a ton of speedup from this, but figure it is a good change anyway.

4a77dfb042 [FRONTEND] Complete rewrite of the runtime (#644)
This PR completely rewrites the runtime of Triton to be more lean and
clearly separate the compilation step from the just-in-time caching logic.
This should substantially reduce launch overhead.

`master`. It shouldn't hurt anything.

5b4c8f221e [BACKEND] Compiler improvements (#557)
This PR adds several optimization capabilities in the compiler backend:
- Now using inline PTX for `tl.store`, making it possible to use things like evict_last
- For A100, mma layout can be directly converted to shared memory
- For A100, an additional "transpose" argument in `dot` allows tensors to be loaded once and used both row- and col- major.
- Fixed liveness analysis; this was broken.
- Now can load/store directly mma layout without converting. Useful for when tl.dot accumulator is initialized with DRAM data inside of an inner loop.
- `tl.dot` can now take LHS inputs in registers when it comes from a previous `tl.dot` instruction. Useful for e.g. fused attention.

This is a more stable commit that produce bitwise identical code to earlier

e85c7a7fc7 Bugfix in ptxas path. (#487)
Bug: "ret" value is destroyed when a failing "ptxas --version" is run
overwriting the previous valid "ret" value.

Fix: keep rets only for those runs which are successful. Pick the first
one
