Just replacing AUTOUPDATE with NOAUTOUPDATE, and removing the autoupdate
script. Tests will still run, but autoupdate may need to be fixed if
significant changes are made.
I noticed this while trying to autoupdate for #4007 (because we verify
that tests have been autoupdated). Autoupdate was likely broken by
#3449.
Trying to run with no changes gives:
```
CHECK failure at testing/file_test/file_test_base.cpp:801: !absl::GetFlag(FLAGS_test_targets_file).empty(): Missing --test_targets_file.
```
This is because the `file_test` rule creates a file with test inputs
that it runs with, which the prebuilt binary doesn't provide.
A local kludge to create a `file_test` target not using prebuilt_binary
showed another error:
```
: CommandLine Error: Option ': CommandLine Error: Option 'parser_debug' registered more than once!
LLVM ERROR: inconsistency in registered CommandLine options
trace_phase' registered more than once!
LLVM ERROR: inconsistency in registered CommandLine options
```
I'm thinking here that the explorer code hasn't been in enough use, and
we're seeing some rot as a consequence. Rather than trying to maintain
it, I'm suggesting to go with NOAUTOUPDATE.
Allow interleaving of STDOUT and STDERR check lines. Put STDOUT lines
after the line they're attached to, and STDERR lines before. If no
STDOUT check line is attached to any line, then put them all at the end
of the file instead.
This is intended to better handle the case where stdout contains
unreplaced mentions of line numbers, and also reflects that stdout is
typically a consequence of the test rather than commentary on it, so
placing it after the test seems likely to read better.
Isolating test execution time (no build time included):
- Linux, `lit` test-per-file: Elapsed time: 28.214s, Critical Path: 13.97s
- Linux, `cc_test`-per-file: Elapsed time: 11.534s, Critical Path: 6.05s
- Linux, merged `cc_test` with 50 shards: Elapsed time: 11.677s, Critical Path: 11.17s
- Mac, `lit` test-per-file: Elapsed time: 295.686s, Critical Path: 20.00s
- Mac, `cc_test`-per-file: Elapsed time: 55.788s, Critical Path: 3.81s
- Mac, merged `cc_test` with 50 shards: Elapsed time: 16.269s, Critical Path: 7.54s

I'm still leaving a handful of `lit` tests to test end-to-end binary execution. This is why testdata directories are split (`lit` tests next to the `explorer` binary, the `cc_test`s next to `ParseAndExecute`).
Relates to https://github.com/carbon-language/carbon-lang/issues/1881
- Add support for `.base` field in structs for [parent class initialization](https://github.com/carbon-language/carbon-lang/blob/trunk/docs/design/classes.md#constructors)
- Disabling base class initialization without `.base`
- Support class constructors (`Create() -> Self`) for base classes
- Direct access to base class(es) attributes with `object.var` remains unaffected
Changes:
- Add `TypeChecker::FieldTypesWithBase` to help assessing if a struct with `base` fields can be converted to a class
- Add a new `base_type()` attribute+getter to `NominalClassDeclaration` to as a first step to allow resolving parametrized classes
- Add a new `base` attribute+getter to `NominalClassValue` that contains the base class `NominalClassValue`. It is currently used mainly to get and set members of a class object.
- Add `Interpreter::ConvertClassWithBase` to build `NominalClassValue` from a init struct, that contains `.base` fields with either `NominalClassValue` or `StructValue`
- Add `FindClassField` to find a field in a class or its base classes
- Remove superfluous `ClassDeclaration::base()` in favor of `ClassDeclaration::base_type()`
Limitations;
- Though some work is done in that direction, parametrized base class where time is not know at the declaration site are not supported. Namely the example below does not compile
```
base class A(T:! Type) {}
class B(T:! Type) extends A(T) {}
```
But this one is functional already
```
base class A(T:! Type) {}
class B extends A(i32) {}
```
