[test] Adjust some 32-bit tests to work both on main and rebranch

* `getelementptr inbounds` -> `getelementptr inbounds nuw`. This
  attribute was introduced in
  llvm/llvm-project#107257 (llvm-project). Match
  it using a wildcard regex, since it is irrelevant to these tests.
* Both the syntax and relative order of the LLVM `nocapture` parameter
  attribute changed in llvm/llvm-project#123181.
  Adjust the FileCheck patterns to expect both syntaxes/orders. This
  change is temporary and will be cleaned up once rebranch is merged
  into main.
