Use blocktype_params_results in lieu of blocktype_to_types.

Remove read_info.rs entirely.

Add `to_compile_error` that converts a WasmResult into a Result<_, CompileError>, use it with `wptype_to_type`. This is a candidate for being moved into shared code.

Many functions had to change to deal with propagating CompileError.
