Update pygments (syntax highlighter for documentation)

Hi,

I hope this gets attention of someone who is able to update software on the web server. The syntax highlighting of many code examples in LangRef is currently broken because an old version of pygments is used on the server that builds the documentation. Significant improvements were done in a recent revision of pygments [1] which is not yet released, but the latest stable version (1.6) should at least fix the cases were the syntax highlighter gives up completely, like in [2].

BTW, even llvm-as is unable to parse the example there because the last line is wrong.

the web server.

I would recommend emailing llvm-admin for that.
