parseVectorKind()

static Optional<std::pair<int, int> > parseVectorKind ( StringRef  Suffix, RegKind  VectorKind  )

static

Returns an optional pair of (#elements, element-width) if Suffix is a valid vector kind.

Where the number of elements in a vector or the vector width is implicit or explicitly unknown (but still a valid suffix kind), 0 is used.
