934bc4e1b3 Move PartitionSpec and Mesh out of experimental and into the sharding namespace. The new API endpoint is jax.sharding.PartitionSpec and jax.sharding.Mesh.

4ca05f428f [call_tf] Use the same platform for TF lowering as the embedding JAX computation 
This requires some changes for abstract evaluation, when
JAX does not use a specific platform.

Also attempt to fix the case when the TF lowering fails because the TF computation
uses a tf.Variable on another device as that used for lowering.

1cead779a3 Add support for Hessenberg and tridiagonal matrix reductions on CPU. 
* Implement jax.scipy.linalg.hessenberg and jax.lax.linalg.hessenberg.
* Export what was previously jax._src.lax.linalg.orgqr as jax.lax.linalg.householder_product, since it can be used with some minor tweaks to compute the unitary matrix of a Hessenberg reduction.
* Implement jax.lax.linalg.tridiagonal, which is the symmetric (Hermitian) equivalent of Hessenberg reduction.

None of these primitives are differentiable at the moment.

ab8cde9ed4 Add support for the hermitian option on jnp.linalg.pinv. 
Improve the pinv implementation to avoid computing an unnecessary reduction: svd sorts its singular values so we don't need to use amax() to find the largest one.
Avoid explicitly forming the identity matrix in the pinv JVP.

cc5171034f Add new config jax_persistent_cache_min_compile_time_secs. 
This replaces `jax_persistent_cache_min_instruction_count` introduced
in https://github.com/google/jax/pull/12798, since gating on the
compile time seems strictly better than gating on the instruction
count (except maybe that the instruction count is more deterministic,
but I don't think that's a big deal).

I defaulted to 1 second as the minimum threshold based on the same
flax wmt example
(https://github.com/google/flax/tree/main/examples/wmt) numbers from

9ab88071a7 Avoid loading scipy eagerly. 
scipy accounts for around 400ms of the 900ms of JAX's import time. By
loading scipy lazily, we can improve the timing of `import jax` down to
about 500ms.

Fixes #12582. Setting the env var `JAX_RAISE_PERSISTENT_CACHE_ERRORS=true` will revert to the original behavior of raising exception instead of warning.

Also makes JAX_DUMP_IR_TO work when the persistent cache is enabled.

5527966b27 [JAX] Deprecate .to_py() property on arrays. Implement __array__ instead. 
.to_py() was something of an accidental export from the JAX array classes. There are other mechanisms to turn a JAX array into a NumPy array, including `np.asarray(x)` and `jax.device_get(x)`. Deprecate this mechanism because it is redundant.
