Add metadata (e.g.
bool requiresScalarEpilogue () const
Returns true if this Group requires a scalar iteration to handle gaps.

class llvm::InterleaveGroup< InstTy >

The group of interleaved loads/stores sharing the same stride and close to each other.

Each member in this group has an index starting from 0, and the largest index should be less than interleaved factor, which is equal to the absolute value of the access's stride.

E.g. An interleaved load group of factor 4: for (unsigned i = 0; i < 1024; i+=4) { a = A[i]; // Member of index 0 b = A[i+1]; // Member of index 1 d = A[i+3]; // Member of index 3 ... }

An interleaved store group of factor 4: for (unsigned i = 0; i < 1024; i+=4) { ... A[i] = a; // Member of index 0 A[i+1] = b; // Member of index 1 A[i+2] = c; // Member of index 2 A[i+3] = d; // Member of index 3 }

Note: the interleaved load group could have gaps (missing members), but the interleaved store group doesn't allow gaps.
