V_FMAC_F32 and V_DOT2C_F32_F16 have a dummy src2 operand tied to vdst to inform passes that the instructions read the dst operand. The VOPD versions of these instructions lacked the dummy operand, which was a problem for inserting s_delay_alu. Introduce the dummy src2 operand on the VOPD versions, and fix the VOPD operand tracking logic to account for it. Reviewed By: dp Differential Revision: https://reviews.llvm.org/D136629
