ABI compatibility for struct/union function arguments passed by value.
The passing of struct/union arguments by value implemented in the verified part of CompCert is not compatible with the ARM, PowerPC and x86 ABI. Here we enrich the StructReturn source-to-source emulation pass so that it implements the calling conventions defined in these ABIs. Plus: for x86, implement the returning of struct/union results by value in a way compatible with the ABI.
