[PATH] Use getPreferredAlignment instead for getABIAlignment when checking global variables in lint

[Julien Lerouge]

Hello,

The attached patch changes Lint.cpp to use the preferred alignment instead of the ABI alignment for global variables defined in the current module that don’t have any explicit alignment set.

computeKnownBits() in ValueTracking.cpp is doing the same thing, so this patch is just fixing an inconsistency that is causing lint warnings when it really shouldn’t.
