    [ptr-compr][turbofan][CSA] Adding the CompressedHeapConstant node · a31b36e0
    Santiago Aboy Solanes authored
    CompressedHeapConstant is used in the DecompressionElimination Reducer to
    create compressed HeapConstant values. It won't appear in the graph
    up until that point.
    
    This CL enables back the disabled tests in DecompressionElimination, as
    well as generating the CompressedHeapConstant in that reducer.
    
    The RelocInfo has already been added for x64 but not for arm64. Therefore,
    the x64 version is now doing the mov on 32 bits. The support for ARM will
    come in a following CL, and for now it is doing the mov in 64 bits.
