    [turbofan][x64] Improve code generation for external reference access. · 7500e507
    bmeurer authored
    Properly fold external reference access into memory operands whenever
    possible, i.e. for accessing the allocation top/limit, similar to what
    we do in Crankshaft and hand-written native code. This only works when
    the serializer is disabled, i.e. doesn't apply to the stubs in the
    snapshot (for now). This reduces register pressure especially around
    allocations where we'd currently need two registers to hold both the
    allocation top and limit pointers in registers (on x64).
