We have 3 variants for dpp vopc. For example:
V_CMP_LE_U32_e32_dpp_gfx11
V_CMP_LE_U32_e32_dpp_w32_gfx11
V_CMP_LE_U32_e32_dpp_w64_gfx11
Last two have (vcc/vcc_lo) in AsmString.

I did not see a nice way to differentiate between them so I added two new tables (could not be one because there is not a common tablegen class).
