[RFC] Differentiating between clang that's build with/without assertions using version information

Hi,

I would like to add an extension to Clang’s version output that adds a “(+asserts)” string when Clang is built with assertions enabled. This is a useful way to differentiate between clang binaries that have assertions enabled and the ones that don’t if they are based on the same version.

I put up a patch for review:
https://reviews.llvm.org/D58559

Please let me know what you think.
Cheers,
Alex
