This change, when enabled, stages out all primitive calls in the dynamic
scope of a jitted, pmapped, or control flow function, rather than only
staging out based on data dependence. One improvement is that jitted
functions can consume less memory, by avoiding instantiating large
constants at trace time, and cause less memory fragmentation as well. It
also simplifies several internals.

* Make check_dtypes, atol, and rtol keyword-only arguments in jax.test_util APIs.
Default to check_dtypes=True.
Remove explicit usages of check_dtypes=True from tests. This mostly just removes visual noise from tests. Testing for exact type equality is the sensible default, although there are cases where opting out makes sense.
No functional changes intended.
* Fix a number of lax reference implementations to preserve types.
At head the following fails:
```python
>>> import jax
>>> import jax.numpy as jnp
>>> jax.config.update('jax_numpy_rank_promotion', 'raise')
>>> jax.nn.one_hot(jnp.ones([8]), 512)
...
ValueError: Operands could not be broadcast together for equal on shapes (8, 1) (512,) and with the config option jax_numpy_rank_promotion='raise'. For more information, see https://jax.readthedocs.io/en/latest/rank_promotion_warning.html.
```
* Added dtype arg for NN initializer factory methods
Initializer factories in jax/nn/initializers.py (such as
uniform(), normal(), glorot_normal(), etc) now have
an optional `dtype` argument.
The value passed in that argument becomes the
default value for the same `dtype` argument
of the initializer function returned by the factory.
* fixed failed test for delta_orthogonal in d12cdc47
* Change test tolerance logic not to choose tolerance values based on flags (in particular, --jax_enable_x64).
We would like to move away from having global flags to enable 64-bit mode. We therefore need other methods to select test tolerances. Instead, use a per-type default tolerance, and allow tests to pass per-type dictionaries of tolerances as atol and rtol values. Fix up a number of tolerances to make tests pass.
* Fix test tolerances.
* Fix dtype canonicalization for test tolerances.
* Relax core test_vjp tolerance.
