[PATCH] D41044: Implementation of -fextend-lifetimes and -fextend-this-ptr to aid with debugging of optimized code

I should note we've had at least one request to make this specifiable per-function, which would mean defining an attribute to control the emission of the fake-use intrinsics.  Doing the feature that way would be consistent with 'optnone'.
