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.
I've migrated the toolchain autoupdate scripts here, I just need a
little more time to do the explorer side (which I need to check
performance, that may require multithreading as we do in the current
script). However, this felt substantial enough to share and it means I
can handle autoupdate in more of the toolchain, including preparatory
work for autoupdate on multi-file tests.
Once explorer is done I'll remove the old script.
This is a simplification of the construction, although somewhat limiting
(it means that the caller can't register the same file multiple times,
though I stopped doing that anyways since it was causing confusion).
What this more importantly _allows_ is logic on the FileTestBase child
itself that's not test-specific -- in particular, autoupdate
functionality which wouldn't use RUN_ALL_TESTS.

This is sufficient to convert remaining toolchain tests to file_test. %s
and %t are currently used. While #2978 might use %T with lit, I think
that's resolving a lit-specific issue that's not necessary when
TEST_TMPDIR is readily available for any necessary operations (i.e.,
setting the working directory). With ARGS, I think it's feasible to
switch to file_test without %T.
Also adds documentation to file_test_base.h, which was starting to feel
like a significant gap.
This is not yet handled by autoupdate, but I'm eyeing that next.
This pr creates the object file for the carbon code that returns either
0 or 1. The command to convert the object code to binary is `clang
<object_file_name> -o <binary_name>`
