Does this need anything other than a rebase? |

This adds a new effect :nothrow_if_inbounds that basically does what it says on the tin. Running #43852 through its paces, I've found it highly effective, except in cases where a function was only nothrow because of a boundscheck with unknown bounds. This PR adds support to make use of @inbounds annotations to still let inlining remove calls that are nothrow except for an unknown boundscheck.

Is this still in-progress or dead? There look like a lot of conflicting files |

I think this is dead. We changed the way that inbounds and effects interact, so we'd have to rethink this anyway. |
