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.
