    compiler: in composite literals use temps only for interfaces

    For a composite literal we only need to introduce a temporary variable
    if we may be converting to an interface type, so only do it then.
    This saves over 80% of compilation time when using gccgo to compile
    cmd/internal/obj/x86, as the GCC middle-end spends a lot of time
    pointlessly computing interactions between temporary variables.

    For PR debug/101064
    For golang/go#46600
