Summary:
Libc++ frequently has the need to parse more than just the builtin *test keywords* (`RUN`, `REQUIRES`, `XFAIL`, ect). For example libc++ currently needs a new keyword `MODULES-DEFINES: macro list...`. Instead of re-implementing the script parsing in libc++ this patch allows `parseIntegratedTestScript` to take custom parsers.
This patch introduces a new class `IntegratedTestKeywordParser` which implements the logic to parse/process a test keyword. Parsing of various keyword "kinds" are supported out of the box, including 'TAG', 'COMMAND', and 'LIST', which parse keywords such as `END.`, `RUN:` and `XFAIL:` respectively.
As an example after this change libc++ can implement the `MODULES-DEFINES` simply using:
```
mparser = IntegratedTestKeywordParser('MODULES-DEFINES:', ParserKind.LIST)
parseIntegratedTestScript(test, additional_parsers=[mparser])
macro_list = mparser.getValue()
```

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`.)
