* config/i386/i386.c (construct_container): Split static issued_error
flag into issued_sse_arg_error, issued_sse_ret_error and
issued_x87_ret_error. Issue a daignostic if the x86-64 ABI
requires the use of x87 registers and the user explicitly
specified the -mno-80387 command line option.
* gcc.target/i386/amd64-abi-2.c: New test case.
