6fd5a6000b Make the demanded bits/elements optimizations preserve debug line information.
I'm not sure this is quite ideal, but I can't really think of any better way to do it.

ef819d0ed8 Start trying to make InstCombine preserve more debug info. The idea here is to set the debug location on the IRBuilder, which will be then right location in most cases. This should magically give many transformations debug locations, and fixing places which are missing a debug location will usually just means changing the code creating it to use the IRBuilder.
As an example, the change to InstCombineCalls catches a common case where a call to a bitcast of a function is rewritten.

Chris, does this approach look reasonable?
