Changes: - Moves object creation code from crates/jit/object.rs to the creates/obj (as ObjectBuilder) - Removes legacy crates/obj/function.rs - Removes write_debugsections
This is the wasmtime-jit crate, which contains JIT-based execution
for wasm, using the wasm ABI defined by wasmtime-environ and the
runtime support provided by wasmtime-runtime.
Most users will want to use the main wasmtime crate instead of using this
crate directly.
