Port bbb1b345

Original Commit Message:

    Adds support for emitting data with a reloc info to enable support
    for HeapObjects for immediate deopt args, required by dynamic check maps.

    In order to do this, a new DATA_EMBEDDED_OBJECT relocinfo type is added.
    This represents a raw object inserted into the instruction stream. For
    x64/ia32 it is treated the same as FULL_EMBEDDED_OBJECT, but on
    Arm/Arm64 this behaves differently since it points directly to the
    embedded object pointer rather than to an instruction that loads it.
