This will simplify integration of this code into LLVM -- The
Simple-Packed-Serialization code can be copied near-verbatim, but
WrapperFunctionResult will require more adaptation.
WrapperFunctionResult is a C++ wrapper for __orc_rt_CWrapperFunctionResult
that automatically manages the underlying struct.
The Simple Packed Serialization (SPS) utilities support a simple serialization
scheme for wrapper function argument and result buffers:
Primitive typess (bool, char, int8_t, and uint8_t, int16_t, uint16_t, int32_t,
uint32_t, int64_t, uint64_t) are serialized in little-endian form.
SPSTuples are serialized by serializing each of the tuple members in order
without padding.
SPSSequences are serialized by serializing a sequence length (as a uint64_t)
followed by each of the elements of the sequence in order without padding.
Serialization/deserialization always involves a pair of SPS type tag (a tag
representing the serialized format to use, e.g. uint32_t, or
SPSTuple<bool, SPSString>) and a concrete type to be serialized from or
deserialized to (uint32_t, std::pair<bool, std::string>). Serialization for new
types can be implemented by specializing the SPSSerializationTraits type.
