…tignore (ROCm#563) When jaxlib was built in debug more, an assertion in LLVM code that lazy-loads VHLO dialect could fire, since the code path could execute in a multi-threaded environment, and LLVM dialect repositories aren't thread safe to modify. This patch applies the same changes that upstream makes to fix this: jax-ml@48c8762 (this includes disabling a call to `jax_mlir_ext.enter_multi_threaded_execution(context)` in `mlir.py`. Presumably, the whole functionality related to `enter_multi_threaded_execution()` multithreaded checks isn't ready yet, and it was prematurely rolled into the production code. Manual testing
