[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

[CodeGen] Unify MBB reference format in both MIR and debug output As part of the unification of the debug format and the MIR format, print MBB references as '%bb.5'.

[RISCV] Support lowering FrameIndex Introduces the AddrFI "addressing mode", which is necessary simply because it's not possible to write a pattern that directly matches a frameindex. Ensure callee-saved registers are accessed relative to the stackpointer. This is necessary as callee-saved register spills are performed before the frame pointer is set. Move HexagonDAGToDAGISel::isOrEquivalentToAdd to SelectionDAGISel, so we can make use of it in the RISC-V backend. Differential Revision: https://reviews.llvm.org/D39848 llvm-svn: 320353
