[llvm-dev] [RFC] Setting the current debug loc when the insertion point changes

There's also the opposite problem of the IRBuilder sometimes not being 
able to find a debug location at the insertion point when it is required 
to add one (e.g. when inserting a CallInst into a function that has 
debug info)... another argument for making it explicit!

+1 to this solution. We shouldn't silently change the behavior of the 
existing SetInsertPoint API.
