    This reverts commit eccf1867.
    
    Reason for revert: Speculative revert because it seems to introduce a pretty stable flake on gc stress tests, see https://bugs.chromium.org/p/v8/issues/detail?id=8229
    
    Original change's description:
    > [interpreter] Separate bytecodes for one-shot property loads and stores
    > 
    > Create LdaNamedPropertyNoFeedback and StaNamedPropertyNoFeedback
    > for one-shot property loads and stores. This CL replaces the runtime
    > calls with new bytecodes for named property load stores in one-shot code.
    > the runtime calls needed extra set of consecutive registers and
    > additional move instructions. This increased the size of
    > bytecode-array and possibly extended the life time of objects.
    > By replacing them with NoFeedback bytecodes we avoid these issues.
