Function compile_frontend_from_ast_with_options_full 

pub fn compile_frontend_from_ast_with_options_full(
    ast: Ast,
    interner: ThreadedRodeo,
    preview_features: &PreviewFeatures,
    suppress_comptime_dbg_print: bool,
) -> MultiErrorResult<CompileState>

Like compile_frontend_from_ast_with_options, but additionally lets the caller suppress the on-the-fly stderr print of comptime @dbg output.
