[llvm] Handle Windows line endings in x86-fold-tables.td test (PR #112997)

[Daniel Paoliello via llvm-commits]

https://github.com/dpaoliello created https://github.com/llvm/llvm-project/pull/112997

The x86-fold-tables.td has been failing for me and in CI if Git happens to decide to check out the baseline file with Windows line endings.

This fix for this is to add the `--strip-trailing-cr` option to diff to normalize the line endings before comparing them.
