Stop setting the target milestone unless it is a regression.

On 32bit, -mno-avx/-mno-sse/-mno-mmx changes ABI for
1. Vector returns.
2. Vector parameters without varargs.
On 64bit,
1. -mno-avx/-mno-sse changes ABI for
a. Float/Vector and aggregate with float/vector returns.
b. Float/Vector and aggregate with float/vector parameters.
2. -mno-i387 changes ABI for
a. long double and aggregates with long double returns.

The ABI warnings are inconsistent:
bash-3.2$ cat u3.i
typedef long long __m128i __attribute__ ((__vector_size__ (16),
__may_alias__));
__m128i
bar2 (void)
{
__m128i x = (__m128i) { 0, 0 };
return x;
}
bash-3.2$ gcc -S -mno-sse u3.i
u3.i: In function bar2:
u3.i:5: error: SSE register return with SSE disabled
bash-3.2$ gcc -S -mno-sse u3.i -m32
bash-3.2$
construct_container has
/* We allowed the user to turn off SSE for kernel mode. Don't crash if
some less clueful developer tries to use floating-point anyway. */
But we issue an error.
