Log:
        PR target/66047
        * i386.c (ix86_function_sseregparm): Only return -1 if local function
        with implied regparm is called from -mno-sse function.
        (init_cumulative_args): Output error if ix86_function_sseregparm
        return -1 and SSE register would be needed.
        (function_arg_advance_32): Likewise.
        (function_arg_32): Likewise.
        * i386.h (ix86_args): Add decl field.
        * gcc.target/i386/pr66047.c: New testcase.
