Using wasmer to implement a compiler

[bcpeinhardt]

Hey there!
I'm in the early stages of figuring out how to add WASM as a target for the Gleam programming language. Gleam is a functional statically typed language that compiles to Erlang and/or JavaScript. I'd like to add WASM to that list of targets.

The compiler is already set up well for generating code from the parsed AST, so I figure I'll produce WAT, use your llvm compiler to optimize the naive wasm and then set up the compiler cli to use the wasmer runtime as a default for a command like gleam run --target=webassembly. The compiler and cli are implemented in rust btw.
A lot of this depends on the GC proposal but lets just ignore that for a minute :)

I'm starting this discussion because I'm still a little unclear on the available tools and would love to be pointed to the more relevant tools for this task/ informed of a more efficient use of the wasmer toolchain.
