cc-ing llvmdev to get feedback.

this patch is not the end of development,
rather are solid base that folks can start using now.
I'm still working on better error handling, more tests,
fixes for some corner cases, debug gen, few optimizations, etc.
I can keep posting next versions, but the patch will
only get bigger which is against 'incremental changes' policy.
I would prefer to get this base in and keep working
in the tree. What is the way forward here?
Since it's not build by default and doesn't touch core,
it shouldn't cause any breakage, but
may be someone can trigger buildbot run for this patch?
