[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

[RISCV] Enable emission of alias instructions by default This patch switches the default for -riscv-no-aliases to false and updates all affected MC and CodeGen tests. As recommended in D41071, MC tests use the canonical instructions and the CodeGen tests use the aliases. Additionally, for the f and d instructions with rounding mode, the tests for the aliased versions are moved and tightened such that they can actually detect if alias emission is enabled.
