3; This tests that a callsite which is determined to be hot based on the caller's
4; entry count and the callsite block frequency gets the hot-callsite-threshold.
5; Another callsite with the same callee that is not hot does not get inlined
6; because cost exceeds the inline-threshold. inlinthint-threshold is set to 0
7; to ensure callee's hotness is not used to boost the threshold.
