[Damon Fenacci]

This reverts _8326615: C1/C2 don't handle allocation failure properly during initialization (RuntimeStub::new_runtime_stub fatal crash)_ (commit 633fad8).
The fix increased the code cache but was incomplete and didn't fix the underlying issue with code cache allocation potentially crashing.
