<pre>This patch fixes a bad MachineOperand access in vector FMA commuting. The bad
access triggers an assert on debug builds. It may cause incorrect code to be
generated with release builds.

[RISCV] Fix reporting of incorrect commutable operand indices
This patch fixes an issue where RISCV's `findCommutedOpIndices` would
incorrectly return the pseudo `CommuteAnyOperandIndex` as a commutable
operand index, rather than fixing a specific index.
