0be1dd284d Recommit r287403 (reverted in r287804): [lit] When setting SDKROOT on Darwin, use '--sdk macosx' to find the right SDK path.
This shouls now be safe and not break any more bots.  It's strictly better to use '--sdk macosx', otherwise xcrun can return weird things for example when you have Command Line Tools or the SDK installed into '/'.

53d343b998 [lit] Run unit tests as part of lit test suite
Summary:
The Python file `utils/lit/lit/ShUtil.py` contains:

1. Logic used by lit itself
2. A set of unit tests for that logic, which can be run by invoking
  `python utils/lit/lit/ShUtil.py`

Move these unit tests to a `tests/unit` subdirectory of lit, and run
the tests as part of lit's test suite. This ensures that, should the
lit test suite be included in LLVM's own regression test suite, these
unit tests will also be run.

(Instructions on how to run lit's test suite can be found in
`utils/lit/README.txt`.)

56f40f8937 [lit] Remove (or allow specific) unused imports
Summary:
Using Python linter flake8 on the utils/lit reveals several linter
warnings designated "F401: Unused import". Fix or silence these
warnings.

Some of these unused imports are legitimate, while some are part of lit's API.
For example, users of lit expect to be able to access `lit.formats.ShTest` in
their `lit.cfg`, despite the module hierarchy for that symbol actually being
`lit.formats.shtest.ShTest`. To silence linter errors for these lines,
include a "noqa" directive.

6eb10d97ee [lit] Use argparse instead of optparse
Summary:
optparse is deprecated in Python 2.7, which is the minimum version of
Python required to run the LLVM test suite. Replace its usage in lit
with argparse, optparse's 2.7 replacement module.

argparse has several benefits over optparse, but this commit does not
make use of those benefits yet. Instead, it simply uses the new API,
and attempts to keep the number of changes to a minimum.

Confirmed that lit's test suite, as well as LLVM's regression test suite,
still pass with these changes.

47cdc1615e [lit] Compare to None using identity, not equality
Summary:
In Python, `None` is a singleton, so checking whether a variable is
`None` may be done with `is` or `is not`. This has a slight advantage
over equiality comparisons `== None` and `!= None`, since `__eq__` may
be overridden in Python to produce sometimes unexpected results.

Using `is None` and `is not None` is also recommended practice in
https://www.python.org/dev/peps/pep-0008:

> Comparisons to singletons like `None` should always be done with `is` or
> `is not`, never the equality operators.

This variable is used by ASan (and other sanitizers in the future)
on s390x-linux to override a check for CVE-2016-2143 in the running
kernel (see revision 267747 on compiler-rt).  Since the check simply
checks if the kernel version is in a whitelist of known-good versions,
it may miss distribution kernels, or manually-patched kernels - hence
the need for this variable.  To enable running the ASan testsuite on
such kernels, this variable should be passed from the environment
down to the testcases.

89f76ce51d [lit] Improve logging with file redirection.
- This will cause lit to automatically include the first 1K of data in
   redirected output files when a command fails (previously if the command
   failed, but the main point of the test was, say, a `FileCheck` later on, then
   the log wasn't helpful in showing why the command failed).

bf67aefcd0 [lit] Improve readability of failing scripts.
- This only applies to scripts executed by the _internal_ shell script
   interpreter.

 - This patch reworks the log to look more like a shell transcript, and be less
   verbose (but in the interest of calling attention to the important parts).

Here is an example of the new format, for commands with/without failures and
with/without output:
```
$ true
$ echo hi
hi

$ false
note: command had no output on stdout or stderr
error: command failed with exit status 1

```

960b5867c5 Add "REQUIRES-ANY" feature test
Summary:
This patch adds a "REQUIRES-ANY" feature test that is disjunctive. This marks a test as `UNSUPPORTED` if none of the specified features are available.

Libc++ has the need to write feature test such as `// REQUIRES-ANY: c++98, c++03`  when testing of behavior that is specific to older dialects but has since changed.

d5ebabfb3e [lit] Add %:[STpst] to represent paths without colons on Windows.
Summary:
We need these variables to concatenate two absolute paths to construct
a valid path. Currently, %t\%t is, for example, expanded to C:\foo\C:\foo,
which is not a valid path because ":" is not a valid path character
on Windows. With this patch, %t will be expanded to C\foo.
