I wonder if we can have the ability to disable constant folding for a few arguments. This will help the compile time for functions with default arguments. |
This allows constant-folding NamedTuple constructors, in turn allowing constant prop through keyword arguments.

Can this make it into v1.5 or is that unsafe? |

I think JuliaLang#35976 is a pretty big deal since it makes all of SciML suddenly infer a lot better, and probably another big library that's splatting keyword arguments. So I added a note to the compiler/runtime improvements.

This might make the compiler very slightly slower, but fortunately I don't see a significant effect, maybe half a second building Base. The extra type info definitely seems worth it.
