max-time.py:
Windows does not have a native `sleep` command, use `time.sleep()` in
Python instead.
max-failures.py:
The max-failure test reused the shtest-shell test inputs instead of
defining its own "test domain". However, the output of this
shtest-shell "test domain" is slightly different on Windows, which now
bites us since we made the max-failures test stricter. Let's define
our own "max failures" test domain.
Fixup for cbe42a9d5f. Increase values for testing the overall lit
timeout (--max-time) which wasn't enough for the test to complete on
very slow build bots.
Track and print the number of skipped tests. Skipped tests are tests
that should have been executed but weren't due to:
* user interrupt [Ctrl+C]
* --max-time (overall lit timeout)
* --max-failures
This is part of a larger effort to ensure that all discovered tests are
properly accounted for.
Add test for overall lit timeout feature (`--max-time` option) to
observe skipped tests. Extend test for `--max-failures` option.

The LitConfig is shared across the whole test suite. However, since
enabling recursive expansion can be a breaking change for some test
suites, it's important to confine the setting to test suites that
enable it explicitly.
Note that other issues were raised with the way recursiveExpansionLimit
operates. However, this commit simply moves the setting to the right
place -- the mechanism by which it works can be improved independently.

The shtest-inject test relied on being executed in "single process" mode
and started to fail with a `PicklingError` after it was removed:
```
Can't pickle <class 'lit.TestingConfig.CustomFormat'>: attribute
lookup lit.TestingConfig.CustomFormat failed
```
This happened because the test config has to be serialized to the worker
process, but apparently the `CustomFormat` class defined inline is not
serializable.
This change allows passing the tested functionality (preamble_commands)
directly to `lit.formats.ShTest` so we can use it directly in the test.
This allows defining substitutions in terms of other substitutions. For
example, a %build substitution could be defined in terms of a %cxx
substitution as '%cxx %s -o %t.exe' and the script would be properly
expanded.

This allows creating custom test formats on top of `executeShTest` that
inject commands at the beginning of the file being parsed, without
requiring these commands to physically appear in the test file itself.
For example, one could define a test format that prints out additional
debug information at the beginning of each test. More realistically,
this has been used to define custom test formats like one that supports
compilation failure tests (e.g. with the extension `compile.fail.cpp`)
by injecting a command that calls the compiler on the file itself and
expects it to fail.
Without this change, the only alternative is to create a temporary file
with the same content as the original test, then prepend the desired
`// RUN:` lines to that file, and call `executeShTest` on that file
instead. This is both slow and cumbersome to do.

It would appear that the removal of this lit feature was incomplete

the remaining tests to bring the bots back to green. I would encourage the

Fail early, when we discover no tests at all, or filter out all of them.
There is also `--allow-empty-runs` to disable test to allow workflows
like `LIT_FILTER=abc ninja check-all`. Apparently `check-all` invokes
lit multiple times if certain projects are enabled, which would produce
unwanted "empty runs". Specify via `LIT_OPTS=--allow-empty-runs`.
There are 3 causes for empty runs:
1) No tests discovered. This is always an error. Fix test suite config
or command line.
2) All tests filtered out. This is an error by default, but can be
suppressed via `--alow-empty-runs`. Should prevent accidentally
passing empty runs, but allow the workflow above.
3) The number of shards is greater than the number of tests. Currently,
this is never an error. Personally, I think we should consider
making this an error by default; if this happens, you are doing
something wrong. I added a warning but did not change the behavior,
since this warrants more discussion.

Without this patch, when using lit's internal shell, if `not` on a lit

`not` seems useful for some builtins, such as `diff`, so this patch

`not` calling `env` calling an external command appears useful when
the `env` and external command are part of a lit substitution, as in
D65156. This patch supports that by looking through any sequence of
`env` and `not` commands, building the environment from the `env`s,
and storing the `not`s. The `not`s are then added back to the command
line without the `env`s to execute externally. This avoids the need
to replicate the `not` implementation, in particular the `--crash`

Using GNU diff, `--strip-trailing-cr` removes a `\r` appearing before

This patch also adds `--strip-trailing-cr` to some tests that fail on

diff is comparing a file with `\r\n` line endings to a file with `\n`
line endings. Without D68664, lit diff reads those files in text

However, with D68664, lit diff reads the files in binary mode instead

This change updates the lit.cfg file to use llvm_config when it is available, but when it is not, it directly modifies the config object. This makes it possible to run the lit tests standalone without having built llvm (as long as the correct binaries are present in the path such as FileCheck and not).
Because the lit tests don't take a hard dependency on llvm_config, some features such as system-windows have to have definitions in lit's cfg file as well. This is a potential issue as the os features sometimes change names (for example, we went from windows to system-windows, etc.). This can cause drift between lit's tests and the rest of the llvm tests.

Summary:
Various tests in the `lit` testing suite expect specific return codes
and forms of diagnostic message from utility programs. As per
POSIX.1-2017 XCU Section 1.4, Utility Description Defaults, "[the]
format of diagnostic messages for most utilities is unspecified".
The STDERR subsections of the `cat` and `wc` utilities merely indicate
that "[the] standard error shall be used only for diagnostic messages".
The corresponding EXIT STATUS subsections merely indicate, with regard
to errors, an exit value of >0.
The affected tests are updated to accept the applicable diagnostic
message as produced by the utilities on AIX. The exit value is
normalized using `not` as necessary.

This enables lit to work with unicode file names via mkdir, rm, and redirection.
Lit still uses utf-8 internally, but converts to utf-16 on Windows, or just utf-8
bytes on everything else.

Check that we do not crash if a parallelism group is explicitly set to
None. Permits usage of the following pattern.
[lit.common.cfg]
lit_config.parallelism_groups['my_group'] = None
if <condition>:
lit_config.parallelism_groups['my_group'] = 3
[project/lit.cfg]
config.parallelism_group = 'my_group'

From the docs: `class LitTestCase(unittest.TestCase)`
LitTestCase is an adaptor for providing a 'unittest' compatible
interface to 'lit' tests so that we can run lit tests with standard
python test runners.
It does not seem to be used anywhere.

Summary:
Automatically upgrade debugging experience (single process, no thread
pool) when:
1) we only run a single test
2) user specifies `-j1`
Details:
Fix `--max-failures` in single process mode. Option did not have an
effect in single process mode.
Add display feedback for single process mode. Adapted test.
Improve argument checking (require positive integers).
`--single-process` is now essentially an alias for `-j1`. Should we
remove it?

If a user has PYTHONPATH set in the environment, append new entries to
it rather than blindly setting PYTHONPATH to a fixed string. This
allows tests to, for example, find psutil if it is in
PYTHONPATH. Without this change, lit will detect psutil but then
various tests will fail because PYTHONPATH has been overwritten and
psutil cannot be found.

Summary: This is the only test that is still failing on Windows - or rather, it is expected to fail on the bots, but passes on the new bot that we're preparing causing a failure, so I'm going to disable it. Since the test has rarely, if ever, passed on the bots, this should have the same effect and it will unblock the creation of the new bot.
