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.

Summary:
The patch D63957 is to avoid empty string when scrubbing loop comments,
it will replace loop comments to a `#`, that's correct.
But if the line has something else not only loop comments, we will get
a extra `#`.
The patch is to remove the extra `#`.

Prior to the fix, the script was not annotating the first line of
chunk-0.ll. Because of that, a compilation with ./bin/opt was failing.
The extra if-statement ensures that the corner case is covered

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.

Add a new overload of StaticLibraryDefinitionGenerator::Load that takes a triple
argument and supports loading archives from MachO universal binaries in addition
to regular archives.
The LLI tool is updated to use this overload.
Graceful lit shutdown on user keyboard interrupt [Ctrl+C] was a
longstanding goal of mine. After a few refactorings this revision
finally enables it. We use the following strategy to deal with
KeyboardInterrupt:

Printing of a helpful summary for interrupted runs (just as the one for
completed runs) will be tackled in future revisions.

Diagnostics from modules do not have a `main-file` listed. Tweak
`clang-parse-diagnostics-file` to patch this up. Previously, the call

The problem on Windows was that the \b in "..\bin" was interpreted
as an escape sequence. Use r"" strings to prevent that.
