NFC: add early exit in ModuleSummaryAnalysis

Authored by Prazek on Aug 26 2016, 6:51 PM.



Changed this code because it was not very readable.
The one question that I got after changing it is, should we
count calls to intrinsics? We don't add them to caller summary,
so maybe we shouldn't also count them?

LGTM thanks for the cleanup.

We should count intrinsic calls towards the instruction count of the function, because they often do translate to real instructions. Could in fact be more than 1. CallAnalyzer::visitCallSite does some analysis based on the type of intrinsic for the inliner, but I hadn't looked into cloning that here - if we unify the inliner and importer cost analysis we would presumably pick that up.
