[PATCH] D75828: [AssumeBundles] filter usefull attriutes to preserve

[Tyker via Phabricator via llvm-commits]

Herald added a project: LLVM.

This patch will filter attributes to only preserve those that are usefull.
In the case of NoAlias it is filtered out not because it isn't usefull
but because it is incorrect to preserve it as it is only valdi for the
duration of the function.
