Most languages designed to be used by people are not good targets for people creating new languages. Very different set of concerns.

The main ones I am aware of are:

JavaScript: you basically got to if you want to run in a browser.

And C Because it's available on every piece of hardware, it was there before llvm and it doesn't change across hardware (unlike assembly), and most people writing languages know C.

JVM, the .Net CLR etc are not languages. They are intermidate representations like LLVM is. (Approximately). They were designed to be compilation targets. Julia wasn't.

Most of Julia's intersting compiler features are unusual because they need to solve problems Julia has in general other languages wouldn't,or that would not transfer across language boundaries.

The macro stuff is awesome for DSLs. Messing with compiler passed is cool for adding capacities. But I think much more in the sense of implementing a micro language that is closely related to Julia, rather than a full on language that has its own goals and identity (I want to write one for codegolf called Jules that is just Julia except on an error it tries some other lexically nearby code)
