+// 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
