I started the llvm-dev thread for the instruction location tradeoffs (removing the location from instructions to improve profiling support - possibly at the cost of other debug info consumers).
The motivation for this flag is different - for added functionality that's generally (imho/based on conversations so far) pretty well justified for profile needs (the need for function start lines to make profiles somewhat resilient to unrelated code changes, etc - as mentioned in the review/patch description).
