  Log Message:
  -----------
  [AMDGPU] Route no-modifier reg-or-inline AsmParser operands through HwMode predicate

Convert the reg-or-inline operands with no modifiers (MFMA VGPR/AGPR
sources, VCSrc, v_pk_mov_b32, VOP scalar f64) from the fixed-class
isRegOrInlineNoMods to the HwMode-aware isRegOrInlineNoModsByHwMode, so an
odd-aligned tuple is rejected at the offending operand column instead of by
the validateVGPRAlign catch-all.
