Breaks `--trace` into two flags: - `--parser_debug`, which sets the parser debug level (which I haven't dug into piping with `--trace`, but seemed likely to be troublesome) - `--trace_file`, which now the type checker and interpreter will use for trace information (note compile errors should use a different channel) Most of the file edits are just mechanical testdata flag updates: `sed -i 's/--trace/--parser_debug --trace_file=-/' testdata/**/*.carbon` To explain the output paths: - parse/compile errors: stderr - print() calls: stdout - parser tracing: `--parser_debug` option, stdout (formerly stdout if `--trace`) - type check/compile tracing: `--trace_file=<file>`, giving `-` uses stdout (formerly stdout if `--trace`) - return code of executed Carbon code: `--trace_file` if set, stdout if not (formerly stdout always)
