    Reland "[turboprop] Enable tierup to TurboFan with FLAG_turboprop" · 3a6920d2

    This is a reland of e38cb757. This
    was reverted as a potential culprit for a wasm failure. The
    actual revert that fixed the bots is here:
    https://chromium-review.googlesource.com/c/v8/v8/+/2630736.
    This should be safe to reland. I verified locally that the test is
    failing with or without this change.
    
    Original change's description:
    > [turboprop] Enable tierup to TurboFan with FLAG_turboprop
    >
    > FLAG_turboprop was used to test the turboprop compiler without any
    > further tierup to TurboFan. This cl changes:
    > - FLAG_turboprop to also tier up to TurboFan.
    > - Introduces FLAG_turboprop_as_toptier to continue running the
    >   configuration without tierup.
    > - Removes FLAG_turboprop_as_midtier which is same as FLAG_turboprop.
