This patches changes all references to '|&' in bolt tests to instead use the '2>&1 |' syntax for better consistency across testing and so that lit's internal shell can be used to run these tests. This addresses a suggestion made in the comments of this RFC: https://discourse.llvm.org/t/rfc-enabling-the-lit-internal-shell-by-default/80179. Fixes https://github.com/llvm/llvm-project/issues/102388
