This reverts commit aa541f1c9c.
Reason for revert: Reverting due to large regressions for motionmark on M1.
Original change's description:
> [turbofan][arm64] Emit Lsl for Int32MulWithOverflow when possible
>
> Int32MulWithOverflow on arm64 uses a cmp to set flags rather than
> the multiply instruction itself, thus we can use a left shift when
> the multiplication is by a power of two.
>
> This provides 0.15% for Speedometer2 on a Neoverse-N1 machine,
> with React being improved by 0.45%.
