// For all FMA opcodes declared in fma3p_rm_* and fma3s_rm_* multiclasses
// defined below, both the register and memory variants are commutable.
// For the register form the commutable operands are 1, 2 and 3.
// For the memory variant the folded operand must be in 3. Thus,
// in that case, only the operands 1 and 2 can be swapped.
// Commuting some of operands may require the opcode change.
// FMA*213*:
// operands 1 and 2 (memory & register forms): *213* --> *213*(no changes);
// operands 1 and 3 (register forms only): *213* --> *231*;
// operands 2 and 3 (register forms only): *213* --> *132*.
// FMA*132*:
// operands 1 and 2 (memory & register forms): *132* --> *231*;
// operands 1 and 3 (register forms only): *132* --> *132*(no changes);
