  Log Message:
  -----------
  [InstCombine] move shuffle after min/max with same-shuffled operands

This is an intrinsic version of the existing fold for binops.
As a first step, I only allowed min/max, but the code is set
up to make adding more intrinsics easy (with more or less than
2 arguments).

This (and possible follow-ups) are discussed in issue #46238.
