    This reverts commit c46915b9.
    
    Reason for revert: Disasm failures https://ci.chromium.org/p/v8/builders/luci.v8.ci/V8%20Linux%20-%20debug/21727 
    
    Original change's description:
    > [turbofan] Further optimize DataView accesses.
    > 
    > This adds support for unaligned load/store access to the DataView
    > backing store and uses byteswap operations to fix up the endianess
    > when necessary. This changes the Word32ReverseBytes operator to be
    > a required operator and adds the missing support on the Intel and
    > ARM platforms (on 64-bit platforms the Word64ReverseBytes operator
    > is also mandatory now).
    > 
    > This further improves the performance on the dataviewperf.js test
    > mentioned in the tracking bug by up to 40%, and at the same time
    > reduces the code complexity in the EffectControlLinearizer.
