PR28475 PGO is 2% slower than the patch I pasted on msg401743.
The function sizes are almost the same (+1:goto,+1:label), and there is no performance gap between release builds.

I suspect the following.

1. PGO is too sensitive to a function size at near the limit.
2. PR28475 is not fully covered by 44 tests. (msg401346)
