    Revert "[turbofan] Add fast path for Math.pow with small positive integer exponent" · 8d496bed
    Maya Lekova authored
    This reverts commit 83470dee.
    
    Reason for revert: Introduced inconsistencies with the runtime (https://crbug.com/chromium/1339320) and increased inaccuracy
    (https://crbug.com/v8/12996). Even though this is currently not specified, the speed improvement doesn't seem to be worth the
    lower precision.
    
    Bug: chromium:1339320, v8:12996
    
    Original change's description:
    > [turbofan] Add fast path for Math.pow with small positive integer exponent
    >
    > For small positive integer exponents, calculate the result with an inlined loop.
    >
    > This change may improve the average runtime of JetStream2/raytrace for ~8%.
