In the `try_swap_mad_two_srcs()` case, valid_flags() gets called both for the src that we want to try to fold, and for the other src that we are trying to swap to make that possible. It can happen in the 2nd case that a RELATIV src has already been folded. Since `ssa()` returns non- null in both the `IR3_REG_SSA` and `IR3_REG_ARRAY` cases (in the later case, it is the dependent array access that the current instruction cannot be moved ahead of), we need to explicitly check that the src reg we are looking at is still an SSA src.
