//
// This pass converts operations on vector types to operations on their
// element types.
//
// For generic binary and unary vector instructions, the conversion is simple.
// Suppose we have
// av = bv Vop cv
// where av, bv, and cv are vector virtual registers, and Vop is a vector op.
// This gets converted to the following :
// a1 = b1 Sop c1
// a2 = b2 Sop c2
//
// VectorToScalarMap maintains the vector vreg to scalar vreg mapping.
// For the above example, the map will look as follows:
// av => [a1, a2]
// bv => [b1, b2]
//
// In addition, initVectorInfo creates the following opcode->opcode map.
// Vop => Sop
// OtherVop => OtherSop
// ...
//
// For vector specific instructions like vecbuild, vecshuffle etc, the
// conversion is different. Look at comments near the functions with
// prefix createVec<...>.
