There are a number of little projects like that but I'm not aware of any that have attained liftoff.
Javascript was a weird exception, being rigidly the only thing available in the browser for so long and thus the only acceptable "compile target" for anything you want to run in the browser. In general I can't name very many instances of "write in X and compile it to Y", for some Y that isn't something you are forced to use by a platform, being all that successful. (See also assembler itself.) The Javascript world gives a false signal of this being a viable approach to a project; in general it doesn't seem to be.
(Note this is a descriptive claim, not a normative one. I'm not saying this is how it "should" be. It just seems to be the reality. I love people trying to buck the trend but I am a big believer in realizing you are trying to buck a trend, so you can make decisions sensibly.)
I keep waiting for a LLVM IR reverser. If there's a LLVM IR to foo reverser written, you would be able to use any language supported by LLVM and convert them to foo. It seems like a much better solution than all the disparate one-offs that exist today.
