The patch adds extra diagnostics for the inline cost analysis. The diagnostic is available under the new command line flag ("print-cost-annotation-writer") for the "inline-cost" pass. When enabled along with -debug-only=inline-cost it prints the IR of inline candidate annotated with cost and threshold increase per every instruction. 
This should help analyze inliner decisions.
