  Log Message:
  -----------
  [LLVM][InstCombine][SVE] Refactor sve.mul/fmul combines. (#134116)

After https://github.com/llvm/llvm-project/issues/126928 it's now
possible to rewrite the existing combines, which mostly only handle
cases where a operand is an identity value, to use existing simplify
code to unlock general constant folding.
