[PATCH] [RISCV] Extend getTargetDefines for RISCVTargetInfo
Summary: This patch extend getTargetDefines and implement handleTargetFeatures and hasFeature. and define corresponding marco for those features. Reviewers: asb, apazos, eli.friedman Differential Revision: https://reviews.llvm.org/D44727 Patch by Kito Cheng. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@329278 91177308-0d34-0410-b5e6-96231b3b80d8
