Undoes a chunk of #4125 because nobody's really in favor of keeping the formatting, and it's occasionally caused a crash in Formatter to dominate output (and even when working, it can be verbose; the source location in (5) is often more helpful). Basically goes back to: ``` 4. Check::Context NodeStack: 0. LetIntroducer: no value 1. BindingPattern: inst+15 2. LetInitializer: no value 3. StructLiteralStart: no value inst_block_stack_: 0. block<invalid> {inst+0, inst+1, inst+6, inst+7, inst+8, inst+9, inst+10, inst+11, inst+12} 1. global_init {} pattern_block_stack_: 0. block<invalid> {} param_and_arg_refs_stack: 0. block<invalid> {} args_type_info_stack_: 0. block<invalid> {} 5. alias_of_alias.carbon:15:12: checking StructLiteral let d: c = {}; ^~ ``` Fixes #4145
