Commit ID da5bcec481dc22ad2de2e2c8e5c6e8304a373445
Author Sebastian Buchwald

Fix asm modifiers in add_dpbusd_epi32x2 implementations The accumulator should be an earlyclobber because it is written before all input operands are read. Otherwise, the asm code computes a wrong result if the accumulator shares a register with one of the other input operands (which happens if we pass in the same expression for the accumulator and the operand).
