Please reduce the size of this function.

Also mark this function as hot such that T2 further boosted for the indirect callsite.

Reduce the inline-threshold and size of the bar's body.

----------------

Define another function foo_cold, and add another callsite to bar with foo_cold passed in.

Since for indirect call foo_cold the T2 won't be increased, the second callsite to bar is not inlined.
