[PATCH, i386]: Committed: Mark some of builtin functions const

[Uros Bizjak]

Hello!

Just simple TREE_READONLY mark change on a couple of target builtins. 
This will prevent failure when sqrt() is converted to rsqrt(). Tested on 
x86_64-pc-linux-gnu.

        * config/i386/i386.c (ix86_init_mmx_sse_builtins)
        [__builtin_infq, __builtin_fabsq]: Define usign def_builtin.
        [__builtin_ia32_rsqrtps, __builtin_ia32_rsqrtss]: Define using
        def_builtin_const.

Uros.
