[llvm] [RISCV] Remove stale comments. NFC (PR #94925)

[Craig Topper via llvm-commits]

https://github.com/topperc created https://github.com/llvm/llvm-project/pull/94925

We no longer have _TU pseudo instructions.

I'm not sure if we have any unsuffixed instructions w/o mask w/ passthru w/o policy operand. That case is not covered by the earlier comments. I could find any from a quick audit.

-/// * _TU w/o policy operand -- Has a passthrough operand, and always
-///   represents the tail undisturbed state.
-/// * _TU w/policy operand - Can represent all three policy states.  If
-///   passthrough is IMPLICIT_DEF (or NoReg), then represents "undefined".
-///   Otherwise, policy operand and tablegen flags drive the interpretation.
