re PR target/56186 (function return ABI change for 128-bit types on Win64) 

PR target/56186
        * config/i386/i386.c (function_value_ms_64): Add additional valtype
        argument and improve checking of return-argument types for 16-byte
        modes.
        (ix86_function_value_1): Add additional valtype argument on call
        of function_value_64.
        (return_in_memory_ms_64): Sync 16-byte sized mode handling with
        handling infunction_value_64 function.
