Tobias Tebbi ff22ae80e2 [turbofan][csa] optimize Smi untagging better ... - Introduce new operator variants for signed right-shifts with the additional information that they always shift out zeros. - Use these new operators for Smi untagging. - Merge left-shifts with a preceding Smi-untagging shift. - Optimize comparisons of Smi-untagging shifts to operate on the unshifted word. - Optimize 64bit comparisons of values expanded from 32bit to use a 32bit comparison instead. - Change CodeStubAssembler::UntagSmi to first sign-extend and then right-shift to enable better address computations for Smi indices.
