Haicheng Wu 201b191b82 Recommit "[InlineCost] Use TTI to check if GEP is free." #3 ...

This is the third attemp to recommit r292526.

The original summary:

Currently, a GEP is considered free only if its indices are all constant.
TTI::getGEPCost() can give target-specific more accurate analysis. TTI is
already used for the cost of many other instructions.
