Performance suggestion: TimeSpan.From* complie as const

[Meister1977]

I think, compiler can optimize TimeSpan.From* calls to insert the value as const into the binary instead of calling the methods.

JIT already optimizes this kind of pattern to simple mov with a constant value.

Noting that what the user is asking for may be something more akin to constexpr: dotnet/csharplang#2379

There is no language support for that today and such support is incredibly complex, bringing along numerous considerations and potential implications.

That all being said, the JIT (and by extension AOT) do the right thing and so your machine code ends up being already optimal today.

@KeterSCP , thanks, I did not know how I can check the binary after JIT/AOT, so I had checked only wilt ILSpy. But now, I understand it better. Thanks again your answer.
