Right now I think everyone has the habit of doing an autoupdate then
using source control for a diff. This is offering an option of better
diff output from the test.
For example:
```
TEST: toolchain/driver/testdata/fail_flush_errors.carbon !
Ran 1 tests in 81 ms wall time, 8 ms across threads
testing/file_test/file_test_base.cpp:264: Failure
Value of: SplitOutput(test_file.actual_stderr)
Expected: matches elements with union diff
Actual: { "fail_flush_errors.carbon:22:3: error: name `undeclared1` not found [NameNotFound]", " undeclared1;", " ^~~~~~~~~~~", "", "fail_flush_errors.carbon:31:3: error: `Core.String` implicitly referenced here, but package `Core` not found [CoreNotFound]", " \"undec\\x6Cared2\";", " ^~~~~~~~~~~~~~~~", "", "fail_flush_errors.carbon:35:3: error: name `undeclared2` not found [NameNotFound]", " undeclared2;", " ^~~~~~~~~~~", "", "fail_flush_errors.carbon:43:3: error: name `undeclared3` not found [NameNotFound]", " undeclared3;", " ^~~~~~~~~~~", "", "" }, union diff (- expected, + actual):
=== diff in expected elements 0 to 2:
+ fail_flush_errors.carbon:22:3: error: name `undeclared1` not found [NameNotFound]
undeclared1;
^~~~~~~~~~~
=== diff in expected elements 4 to 9:
"undec\x6Cared2";
^~~~~~~~~~~~~~~~
+ fail_flush_errors.carbon:35:3: error: name `undeclared2` not found [NameNotFound]
undeclared2;
^~~~~~~~~~~
=== diff end

Autoupdate would make changes to the file content. Run:
bazel run //toolchain/testing:file_test -- --autoupdate --file_tests=toolchain/driver/testdata/fail_flush_errors.carbon
