// Vector Shifts:
//
// The various saturating and rounding vector shift operations need to be
// represented by intrinsics in LLVM, and even the basic VSHL variable shift
// operation cannot be safely translated to LLVM's shift operators.  VSHL can
// be used for both left and right shifts, or even combinations of the two,
// depending on the signs of the shift amounts.  It also has well-defined
// behavior for shift amounts that LLVM leaves undefined.  Only basic shifts
// by constants can be represented with LLVM's shift operators.
//
// The shift counts for these intrinsics are always vectors, even for constant
// shifts, where the constant is replicated.  For consistency with VSHL (and
// other variable shift instructions), left shifts have positive shift counts
// and right shifts have negative shift counts.  This convention is also used
// for constant right shift intrinsics, and to help preserve sanity, the
// intrinsic names use "shift" instead of either "shl" or "shr".  Where
// applicable, signed and unsigned versions of the intrinsics are
// distinguished with "s" and "u" suffixes.  A few NEON shift instructions,
// such as VQSHLU, take signed operands but produce unsigned results; these
// use a "su" suffix.
