[PATCH] D29937: [RISCV 15/n] Implement lowering of ISD::SELECT_CC

[Alex Bradbury via Phabricator via llvm-commits]

asb created this revision.

There's nothing particular novel here, every backend without a conditional move has something similar to the custom inserter for `SELECT_CC`. Some backends try to use a mix of tablegen patterns and C++ code, for instance to deal with the condition code. I feel it's simpler when just handled in RISCVTargetLowering.
