[llvm] ValueTracking: Skip threadlocal.address in computeKnownBits (PR #88435)

[Nikita Popov via llvm-commits]

An alternative, and I think maybe better, approach to this would be to infer an `align` return attribute on threadlocal.address in InstCombine. This way, not only will computeKnownBits() automatically handle it, but it will also benefit other APIs that directly look at alignment, such as getPointerAlign().
