This patch adds additional entries to the JSON command messages output
by the Swift compiler. It's now possible to get the command executable
("command_executable") and arguments ("command_arguments") as a single
string and array, respectively, rather than having to parse the
shell-escaped command line provided in the "command" key.

* Add the signal number of the terminated task to the output of the driver on platforms for which the signal number is available. The new key in the parseable driver output is "signal".
* Add a test to verify that the signal number is emitted.
* Add documentation for the new "signal" key emitted in the parseable driver output.

- Update the Pygments lexer we use for parsing Swift-like code.
- State more explicitly which highlighting should be used in which
code blocks.
- Disable highlighting altogether in certain cases (such as SIL.rst,
which has equal amounts grammar and SIL excerpts).
This should fix the warnings-as-error issues coming from Sphinx > 1.3.4.
Based on a patch by Jeremy Fergason!
