Alexander Aprelev 0914835773 [vm/inliner] Tweak inlining heuristic, improve List.of inlining.
Builds on top of https://dart-review.googlesource.com/c/sdk/+/228660, introduces vm:vm:always-consider-inlining that tell inliner not to give up inlining of a function.

HashMap constructor got prefer-inline pragma to accommodate shift in inlining away from where it used to be inlined due to large size of inlined HashMap, greater than FLAG_inline_getters_setters_smaller_than heuristic.

Notable performance changes:

JIT (x64)
===
ListCopy.List.of.fixed.100 27.37%
ListCopy.List.of.fixed.2 16.31%

AOT (x64)
===
Empty  -9.978%
InstantiateTypeArgs.Instantiate1  -8.262%
...
ListCopy.List.of.fixed.2 13.73%
ListCopy.spread.num.2 15.51%
ListCopy.List.of.2 15.08%
MapCopy.Map.String.of.Map.100 55.62%
MapCopy.Map.Thing.of.Map.100 56.06%
