Tobias Grosser 4a07bbe3f6 [IRBuilder] Only emit alias scop metadata for arrays, but not scalars
Summary:
There is no need to emit alias metadata for scalars, as basicaa will easily
distinguish them from arrays. This reduces the size of the metadata we generate.
This is especially useful after we moved to -polly-position=before-vectorizer,
where a lot more scalar dependences are introduced, which increased the size of
the alias analysis metadata and made us commonly reach the limits after which
we do not emit alias metadata that have been introduced to prevent quadratic
growth of this alias metadata.

This improves 2mm performance from 1.5 seconds to 0.17 seconds.
