c668d6596e [DOCS] Fix spelling (#664) 
This PR applies minor spelling fix in comments and string literals to
`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
versions. Using commits after this one may lead to slightly different numerics

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

0ab9d67bad uint8, uint16, uint32, and uint64 in kernels (#413) 
A forthcoming PR will update the RNG to use these types.

Also:
- Add tests for the `//`, `<<`, and `>>` operators.
- Change `TensorWrapper` to unwrap objects when the resulting object would be simpler.
- Clean up `throw_unreachable`, since it was triggering compiler warnings.
