[NFC][InstructionCost] Use InstructionCost in Transforms/Scalar/RewriteStatepointsForGC.cpp

In places where we calculate costs using TTI.getXXXCost() interfaces
I have changed the code to use InstructionCost instead of unsigned.
The change is non functional since InstructionCost behaves in the
same way as an integer for valid costs. Currently the getXXXCost()
functions used in this file do not return invalid costs.

See this patch for the introduction of the type: https://reviews.llvm.org/D91174
