Fix PR3016, a bug which can occur do to an invalid assumption:2009-01-19T02:46:28ZChris Lattnersabre@nondot.org2009-01-19T02:46:28Zurn:sha1:c4f85dd708b2b131222f16071e7b8ce9bc8a4fd6
we assumed a CFG structure that would be valid when all code in
the function is reachable, but not all code is necessarily
reachable. Do a simple, but horrible, CFG walk to check for this
case.

Add a helper to remove a branch and DCE the condition, and use it 2008-12-16T20:54:32ZEli Friedmaneli.friedman@gmail.com2008-12-16T20:54:32Zurn:sha1:080efb8cea6255b4f1f373d9cb583d6a6302106b
consistently for deleting branches. In addition to being slightly
more readable, this makes SimplifyCFG a bit better
about cleaning up after itself when it makes conditions unused.

need to delete it afterward.

I don't really see this as being needed, but there is little harm from doing
