[RISCV] Support and tests for a variety of additional LLVM IR constructs Previous patches primarily ensured that codegen was possible for the standard RISC-V instructions. However, there are a number of IR inputs that wouldn't be appropriately lowered. This patch both adds test cases and supports lowering for a number of these cases: * Improved sext/zext/trunc support * Support for setcc variants that don't map directly to RISC-V instructions * Lowering mul, and hence support for external symbols * addc, adde, subc, sube * mulhs, srem, mulhu, urem, udiv, sdiv * {srl,sra,shl}_parts * brind * br_jt * bswap, ctlz, cttz, ctpop * rotl, rotr * BlockAddress operands Differential Revision: https://reviews.llvm.org/D29938 llvm-svn: 318737
