Right now we will attempt to inline methods that have the DoesNotReturn attribute; this is a waste of time and resources, since it's not profitable to inline them and they are virtually always going to be unreachable code anyway.
Noticed this behavior while investigating a regression in LessThanOrEqualAnyBenchmark. It's not responsible for the regression, but it was worsening the pre-optimization IR quality in the benchmark, and this will probably improve startup perf (by reducing time spent in interp codegen) by a tiny amount... I can imagine this actually improving post-optimization code quality in some cases, but I don't know what an example of that would look like.
