Subject: CodeGen: Use range-based for in IntrinsicLowering::AddPrototypes, NFC
X-Git-Url: http://plrg.eecs.uci.edu/git/?p=oota-llvm.git;a=commitdiff_plain;h=d578a48c6d058d8c3ef4287312b5e38dfd9d9924

CodeGen: Use range-based for in IntrinsicLowering::AddPrototypes, NFC

This happens to avoid a host of implicit ilist iterator conversions.
