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.

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`).
There are lots of ways a declaration can be used before we have the information necessary to handle that use. Issue diagnostics for these.
Interleave declaration and type-checking of global declarations so that declaring a later declaration can depend on the results of type-checking an earlier one.
Incorporates tests added in #2266.
Fixes#1394, fixes#1395, fixes#1396.
