Yes, it makes total sense for the garbage collector to be tightly coupled to the memory allocation system, which is also tightly coupled to code generation (as is done in the case of various high-performance managed languages: Java, C#, Haskell, …). I remember hearing a talk a few years ago about a system of the kind you’re talking about - a kind of “managed language” micro-core that ran alongside LLVM so that it could hook into code generation, and was intended to be a kind of toolkit for making new managed languages.
