[llvm] r223365 - Use size_type in the interface exposed by SmallVector.

New Revision: 223365

URL: http://llvm.org/viewvc/llvm-project?rev=223365&view=rev
Log:
Use size_type in the interface exposed by SmallVector.

This matches std::vector and should avoid unnecessary masking to 32 bits
when calling them on o 64 bits system.
