// Patterns used to select SSE scalar fp arithmetic instructions from
// either:
//
// (1) a scalar fp operation followed by a blend
//
// The effect is that the backend no longer emits unnecessary vector
// insert instructions immediately after SSE scalar fp instructions
// like addss or mulss.
//
// For example, given the following code:
//   __m128 foo(__m128 A, __m128 B) {
//     A[0] += B[0];
//     return A;
//   }
//
// Previously we generated:
//   addss %xmm0, %xmm1
//   movss %xmm1, %xmm0
//
// We now generate:
//   addss %xmm1, %xmm0
//
// (2) a vector packed single/double fp operation followed by a vector insert
//
// The effect is that the backend converts the packed fp instruction
// followed by a vector insert into a single SSE scalar fp instruction.
//
// For example, given the following code:
//   __m128 foo(__m128 A, __m128 B) {
//     __m128 C = A + B;
//     return (__m128) {c[0], a[1], a[2], a[3]};
//   }
//
// Previously we generated:
//   addps %xmm0, %xmm1
//   movss %xmm1, %xmm0
//
// We now generate:
//   addss %xmm1, %xmm0

// TODO: Some canonicalization in lowering would simplify the number of
// patterns we have to try to match.
