    This reverts commit 00a757fa.
    
    Reason for revert: Caused perf regressions, https://crbug.com/1280236
    
    Original change's description:
    > Shorten generated code for binary-search switches
    >
    > On some branches of the search tree for a binary-search switch, the
    > input value is sufficiently constrained that we could unconditionally
    > jump to the last possible case rather than checking for value equality.
    > This shortens some builtins by a few instructions and might speed things
    > up, though I expect the effect to be small.
