-/// Multiplies two 64-bit integer values, which are selected from source
-/// operands using the immediate-value operand. The multiplication is a
-/// carry-less multiplication, and the 128-bit integer product is stored in
-/// the destination.

-///
-/// This intrinsic corresponds to the <c> VPCLMULQDQ </c> instruction.
-///
-/// \param __X
-/// A 128-bit vector of [2 x i64] containing one of the source operands.
-/// \param __Y
-/// A 128-bit vector of [2 x i64] containing one of the source operands.
-/// \param __I
-/// An immediate value specifying which 64-bit values to select from the
-/// operands. Bit 0 is used to select a value from operand \a __X, and bit
-/// 4 is used to select a value from operand \a __Y: \n
-/// Bit[0]=0 indicates that bits[63:0] of operand \a __X are used. \n
-/// Bit[0]=1 indicates that bits[127:64] of operand \a __X are used. \n
-/// Bit[4]=0 indicates that bits[63:0] of operand \a __Y are used. \n
-/// Bit[4]=1 indicates that bits[127:64] of operand \a __Y are used.
-/// \returns The 128-bit integer vector containing the result of the carry-less
-/// multiplication of the selected 64-bit values.
