* Don't re-parse wasm for debuginfo This commit updates debuginfo parsing to happen during the main translation of the original wasm module. This avoid re-parsing the wasm module twice (at least the section-level headers). Additionally this ties debuginfo directly to a `ModuleTranslation` which makes it easier to process debuginfo for nested modules in the upcoming module linking proposal. The changes here are summarized by taking the `read_debuginfo` function and merging it with the main module translation that happens which is driven by cranelift. Some new hooks were added to the module environment trait to support this, but most of it was integrating with existing hooks. * Fix tests in debug crate
This is the wasmtime-environ crate, which contains the implementations
of the ModuleEnvironment and FuncEnvironment traits from
cranelift-wasm. They effectively
implement an ABI for basic wasm compilation that defines how linear memories
are allocated, how indirect calls work, and other details. They can be used
for JITing, native object files, or other purposes.
