Rollup merge of #122574 - cuviper:llvm-oom, r=nikic

Register LLVM handlers for bad-alloc / OOM

LLVM's default bad-alloc handler may throw if exceptions are enabled,
and `operator new` isn't hooked at all by default. Now we register our
own handler that prints a message similar to fatal errors, then aborts.
We also call the function that registers the C++ `std::new_handler`.

Fixes #121305
