In presence of dynamic shapes the ThreeFry2x32Descriptor will contain the
value n=-1, and the actual desired output length will be passed as
an additional operand. If the shape is static then the length will be
passed as part of the descriptor.

This CL renames occurrences of "mhlo" in: 1) names, 2) tests, 3) prose in order
to prepare for the upcoming migration.
Unchanged occurrences:
1) Public API that contains "mhlo", e.g. XlaLowering.mhlo and the "mhlo"
argument value in Lowering.as_text and Lowering.compiler_ir.
2) Documentation (changelog, JEPs, IR examples, etc).
3) One rare situation where prose says "StableHLO" and "MHLO" in one sentence,
so both are necessary to disambiguate.

The code for both CUDA and ROCM is almost identical, so with a small shim library to handle the differences we can share almost everything.

We frequently use the pattern
try:
import m
except ImportError:
# do something else.
This suppresses errors when the module can be found but does not import
successfully for any reason. Instead, catch only ModuleNotFoundError so
missing modules are allowed but buggy modules still report errors.
Refactoring only, no functional changes intended.
This should fix a jaxlib build issue on Windows: we only have one constructor of layouts, and it explicitly requests an int64 type.

The Python code in jaxlib to build AMD HIP (ROCM) and NVIDIA CUDA kernels is almost identical. Share that Python code rather than duplicating it.
This change only updates the prng kernels; the idea would be to follow it with similar changes consolidating the other Python code in jaxlib between CUDA and HIP.
