Connie 887f7002b6 [NFC][bolt][test] Change '|&' to '2>&1 |' for lit internal shell support (#102402)
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
