[PATCH] D28693: [InlineCost] Use TTI to check if GEP is free.

[Chandler Carruth via Phabricator via llvm-commits]

While the approach we have of doing cost modeling here has some problems, this does fit in well with what we're doing for zero extends, sign extends, and related. So I'm happy with that side. I'll defer the code side to Chad.
