The internal shell was already threading around a 'cwd' parameter. We
just have to make it mutable so that we can update it as the test script
executes.
If the shell ever grows support for environment variable substitution,
we could also implement support for export.

Summary: I think this is probably a bug, but I'm putting this up for review just to be sure. I think that `lit.util.capture` should decode the resulting string in the same way `lit.util.executeCommand` does.

Summary:
The following types can be encoded and decoded by the json library:
`dict`, `list`, `tuple`, `str`, `unicode`, `int`, `long`, `float`, `bool`, `NoneType`.
`JSONMetricValue` can be constructed with any of these types, and used as part of Test.Result.
This patch also adds a toMetricValue function that converts a value into a MetricValue.

We were already requiring 2.5, which meant that people on old linux distros
had to upgrade anyway.
Requiring python 2.6 will make supporting 3.X easier as we can use the 3.X
exception syntax.
According to the discussion on llvmdev, there is not much value is requiring
just 2.6, we may as well just require 2.7.

Summary:
This patch gives me just enough to leverage the existing functionality in `TestRunner` for use in `libc++` and `libc++abi` .
It does the following:
* Adds the `UNSUPPORTED` tag to `TestRunner.parseIntegratedTestScript`.
* Allows `parseIntegratedTestScript` to return an empty script if a script is not required by the caller.

--xunit-xml-output saves test results to disk in JUnit's xml format. This will allow Jenkins to report the details of a lit run.

As far as I can tell UTF-8 has been supported since the beginning of Python's
codec support, and it's the de facto standard for text these days, at least
for primarily-English text. This allows us to put Unicode into lit RUN lines.

Summary:
This patch changes the way xfail and unsupported tests are displayed.
This output is only displayed when the --show-unsupported/--show-xfail flags are passed to lit.
Currently xfail/unsupported tests are printed during the run of the test-suite. I think its better to display this information during the summary instead.
This patch removes the printing of these tests from when they are run to the summary.

Summary:
This patch add a --show-xfail flag. If this flag is specified then each xfail test will be printed to output.
When it is not given xfail tests are ignored. Ignoring xfail tests is the current behavior.
This flag is meant to mirror the --show-unsupported flag that was recently added.

It was pointed out that this breaks the "virtual test discovery"
mechanism, which allows for narming tests in the test exec root.

It would previously say things like
warning: input 'test/Frontend/foo.c' contained no tests

file. This patch changes the message to the much clearer:
warning: no such file or directory: 'test/Frontend/foo.c'

Clang's lit cfg already detects the currently selected SDK via
"xcrun --show-sdk-path". The same thing should be done for compiler-rt tests,
to make them work on recent OS X versions. Instead of duplicating the detection
code, this patch extracts the detection function into a lit.util method.

This commit prospectively brings the benefits of r198766 to older supported
Python versions (2.5+).

On the other hand, exec(compile()) doesn't work in older Python versions in the
2.x series.
This commit introduces exec(compile()) with a fallback to plain exec(). That'll
hopefully hit the sweet spot in terms of version support.
Followup to r198766 which added enhanced source locations for lit cfg parsing.

Python doesn't do a good job at diagnosing string exec() so use execfile()
where available.
This should be a timesaver when trying to get to the bottom of build bot

exec("exec data in cfg_globals")

Add option -i to prioritize test runs by source file modification time and
previous failure state.
This optimal scheduling reduces typical test-and-fix iteration times to a
matter of seconds by rapidly answering the questions:
1) Did my recent change fix tests that were previously failing?
2) Do the tests I just wrote / modified still work?
The current implementation requires write permissions to the source tree
because it uses mtimes to track failures.
