Auto merge of #77755 - bugadani:perf-calc-dtor, r=ecstatic-morse
Monomorphize `calculate_dtor` instead of using function pointers Change `calculate_dtor` to avoid dynamic dispatching. This change allows the empty functions to be optimized away. Based on the discussion in https://github.com/rust-lang/rust/pull/77754#discussion_r502498970, the performance impact of this change was measured. Perf run results: https://perf.rust-lang.org/compare.html?start=7bc5839e99411aad9061a632b62075d1346cbb3b&end=ffec759ae9bbc4d6d2235ff40ade6723a85bc7cc
