In 90a6c3bd7a ("build: reduce release mode inline tuning on aarch64") we
reduced inlining on aarch64, due to miscompiles.
In 224a2877b9 ("build: disable -Og in debug mode to avoid coroutine
asan breakage") we disabled optimization in debug mode, due to miscompiles.
With clang 18.1, it appears the miscompiles are gone, and we can remove
the two workarounds.
