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.

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.

Summary:
Right now this test is failing on the builtbots on Windows but we have a very similar setup where the test passes. The test is meant to test that specifying a timeout works correctly by running an infnite loop and having it timeout - on the buildbot, the infinite loop doesn't actually execute. This change runs all of the tests in the set using an internal shell rather than an external shell. I expect this will make the test pass which means that either the way the external shell is invoked or the external shell setup on the buildbots is not correct. Regardless of whether the test passes with this change, we'll need to undo this change and have a real fix.
@gkistanova was able to get logs from the buildbot to rule out a number of theories as to why this test is failing, but they didn't have enough information to confirm exactly what the issue is. The purpose of this change is to narrow it down, but if someone has a local repro and can aid in debugging, that would make it much speedier (and less prone to making the bots fail).

This test passes on Windows when using Python 3 but fails when using Python 2, so it needs more investigation before it can be enabled as the bots use Python 2.
llvm-svn: 339184
Summary:
In Python2 'unicode' is a distinct type from 'str', but in Python3 'unicode' does not exist and instead all 'str' objects are Unicode string. This change updates the logic in the test logging for lit to correctly process each of the types, and more importantly, to not just fail in Python3.
This change also reverses the use of quotes in several of the cfg files. By using '""' we are guaranteeing that the resulting path will work correctly on Windows while "''" only works correctly sometimes. This also fixes one of the failing tests.

Summary:
The problem here is that on windows double quotes are used for paths (usually) while single quotes are not. This is not generally a problem for the tests because the lit infrastructure tends to treat both the same. One (and possibly only) exception is when some tests are run in an external shell such as some of the shtest-format tests. In this case on windows the path to python was not created correctly because it had single quotes and the test failed.
This same test is already failing with python 3 which is why our testing missed the new failure. This patch will take care of the immediate failure with python 2 and I'll send a follow up for the python 3 failure.

Summary:
The issue with the python path is that the path to python on Windows can contain spaces. To make the tests always work, the path to python needs to be surrounded by quotes.
This change updates several configuration files which specify the path to python as a substitution and also remove quotes from existing tests.

These two tests are operating on the same test suite, which causes
them to be racy about writing temporary files and can cause spurious
failures. Merge them into one test to avoid the issue.

The test was failing on Windows machines which had bash.exe on PATH (but
not in the so called lit tools dir, containing cmp.exe, grep.exe etc.).
The problem was that the outer lit invocation would load LLVMConfig
from utils/lit/lit/llvm/config.py, which looks up the tools path with
getToolsPath(). That has a surprising side effect of also setting
bashPath, in our case setting it to empty.
The outer lit invocation would thus configure the pdbg0 and pdbg1
substitutions based on not running with bash.
But the inner lit invocation would not load LLVMConfig, so bash
would be found on PATH, that would be used as external shell,
and so the output wouldn't match pdbg0 and pdbg1.
It seems weird to me that getBashPath() will return different results
depending on whether getToolsPath() has been called before, but I
also don't know how to fix it properly.
This commit just relaxes the test case, because there doesn't seem
to be much point in testing for the exact syntax of the run file
as long as it works.

This fixes projects/compiler-rt/test/fuzzer/sigusr.test, which was

When debugging test failures with -vv (or -v in the case of the
internal shell), this makes it easier to locate the RUN line that
failed. For example, clang's test/Driver/linux-ld.c has 892 total RUN
lines, and clang's test/Driver/arm-cortex-cpus.c has 424 RUN lines
after concatenation for line continuations.
When reading the generated shell script, this also makes it easier to
locate the RUN line that produced each command.
To support reporting RUN line numbers in the case of the internal
shell, this patch extends the internal shell to support the null
command, ":", except pipelines are not supported.
To support reporting RUN line numbers in the case of windows cmd.exe
as the external shell, this patch extends -vv to set "echo on" instead
of "echo off" in bat files. (Support for windows cmd.exe as a lit
external shell will likely be dropped later, but I found out too
late.)
