Change the way the version is printed (more verbose, with short hash)
If the user has patches managed by the mq extension, the version and hash
printed are those of the qparent revision (the revision the patches were
applied on top of) instead of tip.
Also fixes a bug: print LLVM revision even if there are local modifications to
it.
Sorry for the long line in the perl file. I have no idea how to break it up.
