Attributor.cpp became quite big and we need to start provide structure.
The Attributor code is now in Attributor.cpp and the classes derived
from AbstractAttribute are in AttributorAttributes.cpp. Minor changes
were required but no intended functional changes.
We also minimized includes as part of this.

lit supports `--time-tests` which will report the 20 slowest tests and
print a nice histogram for test times. This change prints this list and
the histogram rows by decreasing test times. After all, we are most
interested in the slowest tests.
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.

This builds on top of D77184. With this, I can rename my build directory
to a different name and `bin/llvm-lit ../llvm-project/clang/test
../llvm-project/llvm/test` still succeeds.
I haven't tried copying the build dir to a different machine to run
tests there yet, but I tried something like it a few months ago and it
worked back then.
Changes:
- Make configure_lit_site_cfg() store the main / generated config pair
interleaved in the LLVM_LIT_CONFIG_FILES list and postpone converting
it to python code to llvm-lit's CMakeList.
- Pull the relpath code into a new function make_paths_relative() and
call that in llvm-lit's CMakeList, prior to converting the list to
python code.
- Pull the path() function into a variable and use that in llvm-lit's
CMakeList too.

Graceful lit shutdown on user keyboard interrupt [Ctrl+C] was a

The problem on Windows was that the \b in "..\bin" was interpreted
as an escape sequence. Use r"" strings to prevent that.
This reverts commit ab11b9eefa,
with raw strings in the lit.site.cfg.py.in files.
Differential Revision: https://reviews.llvm.org/D77184
Currently, all generated lit.site.cfg files contain absolute paths.
This makes it impossible to build on one machine, and then transfer the
build output to another machine for test execution. Being able to do
this is useful for several use cases:
1. When running tests on an ARM machine, it would be possible to build
on a fast x86 machine and then copy build artifacts over after building.
2. It allows running several test suites (clang, llvm, lld) on 3
different machines, reducing test time from sum(each test suite time) to
max(each test suite time).
This patch makes it possible to pass a list of variables that should be
relative in the generated lit.site.cfg.py file to
configure_lit_site_cfg(). The lit.site.cfg.py.in file needs to call
`path()` on these variables, so that the paths are converted to absolute
form at lit start time.
The testers would have to have an LLVM checkout at the same revision,
and the build dir would have to be at the same relative path as on the
builder.
This does not yet cover how to figure out which files to copy from the
builder machine to the tester machines. (One idea is to look at the
`--graphviz=test.dot` output and copy all inputs of the `check-llvm`
target.)

Having the sync script work for this file seems better

This patch is to remove the redundant SCRUB_LOOP_COMMENT_RE in asm.py

While D68850 allowed functions to be deleted I accidentally saved some
version of the function to be used once a suitable prefix was found.
This turned out to be problematic when the occasionally deleted function
is also occasionally modified. The test case is adjusted to resemble the

--no-threads is a name copied from gold.
gold has --no-thread, --thread-count and several other --thread-count-*.
There are needs to customize the number of threads (running several lld
processes concurrently or customizing the number of LTO threads).
Having a single --threads=N is a straightforward replacement of gold's
--no-threads + --thread-count.
--no-threads is used rarely. So just delete --no-threads instead of
keeping it for compatibility for a while.
If --threads= is specified (ELF,wasm; COFF /threads: is similar),
--thinlto-jobs= defaults to --threads=,
otherwise all available hardware threads are used.
There is currently no way to override a --threads={1,2,...}. It is still
a debate whether we should use --threads=all.

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.
Remove the "serial run" abstraction which bypasses Python's
`multiprocessing.Pool` and instead directly runs tests without spawning
worker processes. This abstraction has not offered the benefits I hoped
it would and therefore does not carry its weight.
In previous commits [1,2] I changed worker.py to only send back the test
result from the worker process instead of the whole test object. This
was a mistake. lit.Test contains fields (e.g., xfials, requires,
unsupported) that are only populated when we actually execute the test,
but are queried when we report the results in the parent process. This
commit essentially reverts the following changes:
[1] a3d2f9b53a

- only complain about duplicate 'sources' lines if they contain
more than 1 elements each (before, 0 and 1 element lists were
counted too). In practice, this only has an effect for
clang/lib/Headers/BUILD.gn
- make the '# NOSORT' diag actually work. This too only affects
clang/lib/Headers/BUILD.gn.
In aggregate, changes to clang/lib/Headers/BUILD.gn still can't
be auto-merged, but for a slighly better reason.
A previous attempt to cleanup module imports broke installing via
pip/setup.py [1]. This should be fixed now.

This minor refactoring allows reducing the amount of processing that
is duplicated when we re-run a flaky test. It also has the nice
side effect that libc++'s current test format supports flaky .sh.cpp
tests, because those are built on top of _runShTest, not executeShTest.
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.

This commit adds a new keyword in lit called ALLOW_RETRIES. This keyword

number of times before it first succeeds.
This work attempts to make the existing test_retry_attempts more flexible
by allowing by-test customization, as well as eliminate libc++'s FLAKY_TEST
custom logic.
